Tesla claims it will have completely self-driving cars on the road - in any weather - within two years.

But what’s the point when you have to stop every 3-4 hours to recharge?

Now this thing - when GM builds an Escalade with self driving technology, and I can fill ‘er up and then go to sleep for nine hours while it whisks the whole family away to grandma’s house - I’ll be first in line.

(I’m not saying Grandma’s house is only 9 hours away, but that’s about how long I can drive on a full tank before we have to stop for fuel, which means the wife and kids can sleep all night if I can just keep my liquid intake - and more particularly output - in check).
