In all honesty, if road lines were the only barrier, then that would be fixed via gov’t mandate. The ultimate test would be safety while driving at night...in the rain or snow.

That said, my own suspicion is that we’re probably less than 20-30 years away from having enough total highway support to make this happen universally.

Read up on how fast the infrastructure in this country is falling apart then reconsider that 20 to 30 years.
