The self driving isn't perfect and you have to pay attention, but man it is nice! We just went to Orlando and back a few weeks ago and the car drove nearly the whole way (Telsa Y). Adds a little time to a long drive and it takes longer to charge than it does to fill a gas tank. But we had time, and charging is much less expensive than this $3 and $4+ gas. At $4 a gallon I'm it is basically getting 120 mpg on home charging. About 55 mpg when charging on the average supercharger.

I've had the self driving lock up the brakes at caution lights. I've had it try to take me on a detour on a dirt road through a cornfield. So you still have to pay attention, but it will make fewer mistakes than a good human driver will. It is especially good in the city and it is an absolute dream on a 4 lane.

Still too pricey for the average person but the price will come down in time. It is certainly a glimpse into the future.
