Iowa man takes Tesla Model Y on 800-mile road trip to Colorado to see if FSD can take him the whole way

With a new era of FSD available, thanks to the Tesla Model Y Juniper, one man from Iowa has embarked on an 800-mile road trip, putting the futuristic software to the test.

Full self-driving, or FSD, has been a pillar of Tesla’s success in 2025.

After giving the green light to fully autonomous cabs with the Robotaxi fleet, the EV company has been confident in its chase of perfection.

So, one man has now taken his Tesla Model Y Juniper on a road trip to push FSD v13, Hardware 4, to its maximum.

New Tesla Model Y ran through lengthy FSD test

Tesla’s full self-driving kit has been upgraded numerous times, with some versions having significantly better results than others.

But the latest version appears to be winning drivers over, as small interstate trips have proven successful for the new EVs like the Model Y Juniper.

This time, one man mapped out an 800-mile trip to Colorado, where he would let the FSD controls have full reign from the driveway to the parking bay.

Highlighted on YouTube by Iowa Tesla Guy, the journey from Boulder, Iowa, to Colorado Springs was designed to hit various charging ports on the way, but left it up to the car to choose its efficiency.

Incredibly, the journey was a breeze. The FSD controls cruised the Tesla Model Y along at around 75mph, being efficient enough to make the trip with just four charging stops.

Along the way, the driver noted just two tiny errors. On one occasion, it failed to note a one-way entrance in a parking lot, but it was easily rectified.

The other blip was in its parking, where the lines in the dirty tracks were hard to spot and the Tesla Model Y jumped over two bays – again, an easy adjustment for the driver to make.

Overall, he was blown away.

“There you have it. The FSD experiment is done. 800 miles from Iowa to Boulder, Colorado, using nothing but FSD – I would say 99.9% of literally all of the driving,” he said.

“When I left this morning from Iowa, it told me that I was going to get here at 6:30pm. Well, what time is it right now? 6:26. I got here four minutes early. Four minutes across 800 miles where the car did all the driving.”

Is FSD the future?

The technology isn’t favored by everyone. In fact, manufacturing behemoth Stellantis just shelved its own FSD program, claiming there’s a lack of appetite for the high-cost software.

But Tesla is ramping up its efforts, dishing out FSD tech to Australia and expanding Robotaxi’s to new cities.

And, it appears that Tesla is also preparing FSD chips in a collaboration with Samsung, which will allow vehicles to become autonomous more easily.

So, it looks like the self-driving tech is working well.

Just stay out of the jungle.
