You get to drive, and the trade-off is someone might get killed. Your comment almost makes me think you haven't driven a car before, because you would remember the dull terror of seeing your life flash before your eyes for the 40th time this year because some moron ran a red and slammed the brakes in the middle of the intersection you were about to cross.
Until recently motor vehicle accidents were a leading cause of death in the US. Saying that self driving would just be a luxury feature is truly a luxury position compared to those that have lost loved ones to drunk driving, speeding, snow, rain, new drivers, old drivers, blind drivers, and any other of the myriad of ways to get yourself killed on a road. All of which would disappear with level 5 self driving.
> That's a far cry from, "with this technology something that took days and $$$$ now takes hours and $"
Extrapolate the future and realize that once self driving is solved for one vehicle it's solved for all of them, and truck/bus/taxi driving as a profession will go bust. Without having to pay human drivers that also need breaks, pensions, health insurance etc. all these services can offer lower prices.
