I decided to use the parallel self parking yesterday for the first time. It scared the crap out of me, it is so fast! It comes up with the warning to be ready to break and I can see why. It whipped into the parking spot so fast I panicked and hit the breaks because I worried that it was going to impact with the car behind. I used it again and the same thing, I hit the breaks. It certainly does a great job getting into the spot! Has anyone just let it go all the way? I have a Tesla Model S and it is so much slower, that I find it too slow and just park it myself. With the rear view cameras on both vehicles making it a breeze to park it myself I hadn't tried the Volt's self parking feature before.
