I would make an exception for snow, but not for rain or night. Although I think being unable to cope with snow is a pretty significant issue.

About "5 years away", I've been reading the same dream of all cars being self driving for so many years. I distinctly remember an after-work party in 2010 where a coworker with a phobia of driving going on about how self driving cars would soon be driving him around. Everything I hear today has been repeated for so long.
