We aren't all on the same page as to how we are visualizing the next few years.
Some are talking about level 4 or 5 autonomy meaning the cars may not have a steering wheel and sleeping in the back seat is acceptable and normal. I think we may get there sooner than some do (and I have been through an IT career too). Percy is right that there will still be deaths but if they are way less than letting humans drive we're going to have to adjust to that or stick with killing lots and lots of people.
For the 2020's I'm seeing more of a level 3/4 autonomy where people will still have to "drive" and be attending to the cars behaviour a lot of the time (or all). However, I see a scenario where we will not be allowed to turn off the autopilot. Instead we will be able to override it for short periods of time only and we better be able to justify out taking over after the fact.
