Be careful what you ask for. Technology is a great benefit, but it has challenges and takes time to be refined. Take you PC for example. For decades systems were plagued with errors, faults, and issues. Remember the BSOD (Blue Screen of Death). Most of the time those problems could be resolved with a quick reboot and perhaps having to redo something in an application which was lost.

Now you want to have technology operate the acceleration, braking, turning, and safety of your vehicle? If something goes wrong, the consequence is not a reboot, it is a collision! Are people truly ready to hand over their lives to unproven technology? It seems a little rash. Perhaps we should move more slowly and be sure it will not be hazardous to our health.
