The "I-70 stare" is a real phenomenon. If you’ve ever driven the 250-mile stretch between Kansas City and St. Louis, you know exactly what I’m talking about. It’s that glazed-over look drivers get after two hours of staring at a flat horizon, dodging erratic semi-trucks, and praying for a glimpse of the Columbia skyline. At Frontier Tesla, we see travelers every day who are looking for a better way to navigate this Missouri corridor. They aren't just looking for a car; they're looking for a co-pilot.
The question we get most often is simple: Is a Tesla Autopilot rental in Missouri actually worth it for the cross-state trek? To answer that, we have to look past the hype and dive into the data, the safety, and the sheer physical toll of the I-70 drive.
Does the Frontier Tesla Rental Include Autopilot for the Highway?
Let’s clear up the most common point of confusion right away. Every single vehicle in the Frontier Tesla fleet comes standard with Autopilot. When you book a Model 3 or Model Y with us, you aren't paying extra for the basic suite of driver-assist features.
Here’s the thing: Tesla’s "Autopilot" is often used as a catch-all term, but it’s important to distinguish what you’re getting. Our rentals include Traffic-Aware Cruise Control and Autosteer. This means the car will maintain your speed relative to surrounding traffic and keep itself centered within its lane. For the long, often monotonous stretches of I-70, this is the "sweet spot" of EV technology. You don't need the car to navigate complex downtown intersections in St. Louis autonomously to feel the benefits; you just need it to take the "micro-adjustments" off your plate during the three-hour highway haul.
The I-70 Corridor: A Stress Test for Any Driver
Interstate 70 is the lifeblood of Missouri, but it’s also a high-stress environment. According to the Missouri Department of Transportation (MoDOT), I-70 carries upwards of 30,000 to 100,000 vehicles per day depending on the segment, with a massive percentage of that being heavy freight.
Driving between KC and St. Louis isn't just about keeping the wheel straight. It’s a constant dance of overtaking slow-moving trucks, managing the "draft" as you pass a 53-foot trailer, and reacting to the sudden slowdowns near Kingdom City or Warrenton. This is where the cognitive load starts to pile up. By the time you reach the Arch or the Country Club Plaza, you’re often more exhausted than you realize.
How Autopilot Handles the I-70 Traffic Between KC and St. Louis
So, how does the tech actually perform in the wild? I’ve driven this route dozens of times in our fleet vehicles, and the experience is transformative.
Managing the Semi-Truck Shuffle
The biggest challenge on I-70 is the sheer volume of logistics traffic. Autopilot uses a suite of cameras and powerful vision-based processing to "see" 360 degrees around the car. When you’re passing a semi-truck, the system is much more precise than a human at maintaining a perfect center-lane position. It doesn't get "intimidated" by the size of the vehicle next to it.
Traffic-Aware Cruise Control (TACC) in Action
Missouri construction is a constant. Whether it's bridge work near Boonville or lane closures near Wentzville, traffic speeds on I-70 can drop from 70 mph to 20 mph in seconds. Tesla’s TACC is remarkably smooth at handling these transitions. Instead of the jerky braking you might experience with older adaptive cruise systems, the Tesla gradually eases off the accelerator, using regenerative braking to slow down while simultaneously putting energy back into the battery. It’s efficient, and it saves your brake pads.
Handling Crosswinds and Road Surface
The Missouri plains are notorious for crosswinds that can buffet a standard rental car, requiring constant steering corrections. The Model 3, with its floor-mounted battery pack, has an incredibly low center of gravity. When you engage Autosteer, the car’s computer makes hundreds of tiny steering adjustments per second to counteract wind and road crowning. You’ll find yourself arriving at your destination without the usual shoulder and neck tension.
Is it Safer to Rent a Self-Driving Capable Car for a Long Road Trip?
Safety is the ultimate metric. While no car is "self-driving" in the sense that you can take a nap, the data suggests that driver-assist systems significantly reduce the risk of accidents.
According to the Tesla Q4 2023 Safety Report, the company recorded one crash for every 5.39 million miles driven in which drivers were using Autopilot technology. For drivers who were not using Autopilot, the figure was one crash for every 1.00 million miles. Compare that to the NHTSA national average of one crash for every 670,000 miles, and the disparity is staggering.
Reducing Human Error
Human error—specifically distraction and fatigue—is responsible for over 90% of highway accidents. On a long road trip like KC to St. Louis, your reaction time naturally slows down after the first 90 minutes. Autopilot doesn't get tired. It doesn't look down at a phone. It doesn't get distracted by a billboard for a giant candy store in Kingdom City. By acting as a safety net, the system can provide emergency braking or lane-departure warnings faster than a human can blink.
The "Safety Shield" Concept
When you rent from Frontier Tesla, you’re encased in a "safety shield." The car’s ultrasonic sensors and cameras are constantly monitoring blind spots that you might miss during a lane change. If you attempt to move into a lane that is occupied, the car will provide an audible alert and steering resistance to pull you back. On a crowded highway like I-70, this feature alone is worth the rental price.
Key Takeaways: Why Autopilot Wins for Missouri Travel
If you're still on the fence, consider these three primary benefits:
- Reduced Fatigue: By handling the steering and speed, the car allows you to focus on high-level situational awareness rather than the mechanics of driving.
- Superior Safety: You are backed by a system that has a statistically proven lower accident rate than human drivers alone.
- Efficiency: Autopilot is optimized for energy consumption, helping you get the most range out of your Tesla between charges.
Logistics: Charging Your Tesla Between KC and St. Louis
One of the biggest "objections" to renting an EV for a cross-state trip is range anxiety. On I-70, this is a non-issue. The Missouri charging infrastructure is robust.
The distance between Kansas City and St. Louis is roughly 250 miles. A Long Range Model 3 can technically make the trip on a single charge in perfect conditions, but we always recommend a quick 15-minute "leg stretch" stop.
- Columbia, MO Supercharger: Located right off the highway, this is the perfect midpoint. You can grab a coffee at a nearby cafe while the car adds 150 miles of range in the time it takes to use the restroom.
- Kingdom City Supercharger: Another excellent option with plenty of amenities nearby.
The car’s navigation system handles all of this for you. You simply plug in your destination in St. Louis, and the Tesla tells you exactly where to stop, for how long, and how many stalls are available. It’s a "brainless" process.
Step-by-Step: Using Autopilot on Your Frontier Tesla Rental
We want you to feel confident the moment you pull out of our downtown pickup location. Here is the quick-start guide to highway Autopilot:
- Engagement: Once you are on I-70 and have reached your desired speed, pull down twice on the gear selector stalk (on the right side of the steering column).
- Visual Confirmation: You’ll see blue lane lines appear on the center touchscreen, and a blue steering wheel icon will illuminate. This means Autosteer is active.
- Hands-On Policy: You must keep your hands on the wheel. The car uses a torque sensor to ensure you are still paying attention. A light "resting" weight is all that’s required.
- Adjusting Speed: Use the right scroll wheel on the steering wheel to increase or decrease your set speed.
- Disengaging: Simply tap the brake pedal or push up once on the gear stalk to take full control instantly.
Addressing the Skeptics: Common Objections
"I don't trust computers to drive." We hear this. And you shouldn't—not 100%. Autopilot is a support system, not a replacement. You are still the captain of the ship. However, once you experience how the car handles a sudden "phantom" slowdown or stays perfectly centered during a thunderstorm near Blue Springs, that skepticism usually turns into a request to buy a Tesla of your own.
"Is it hard to learn?" Not at all. Most of our renters feel completely comfortable with the system within the first 10 miles of highway driving. We provide a full orientation at our downtown pickup spots in both Kansas City and St. Louis to ensure you're ready.
The Verdict: Is it Worth It?
If you value your time, your energy, and your safety, the answer is a resounding yes. Renting a Tesla with Autopilot for the KC to STL drive turns a "chore" into a premium travel experience. You arrive at your meeting in Clayton or your dinner at the Power & Light District feeling refreshed, rather than drained.
At Frontier Tesla, we’ve made it easier than ever to access this technology. With downtown pickups and a fleet of self-driving capable cars, we’re changing the way Missouri moves.
