&gt; If you limit autonomous driving to the main freight routes on the highway, I can see self driving vehicles happening a lot sooner than I previously expected. Like 20 years sooner.<p>It is 100% certain without any doubt whatsoever that this is how it will start. It will start with dedicated interstate roads (or lanes) just for driverless trucks, and then cars.<p>After some time all freeways will be 100% driverless. I don&#x27;t anticipate mixed use (driverless + drivers) ever happening.<p>Local roads (i.e. uncontrolled access) is many many decades away.
