In the piece — titled “Can You Fool a Self Driving Car?” — Rober found that a Tesla car on Autopilot was fooled by a Wile E. Coyote-style wall painted to look like the road ahead of it, with the electric vehicle plowing right through it instead of stopping.
The footage was damning enough, with slow-motion clips showing the car not only crashing through the styrofoam wall but also a mannequin of a child. The Tesla was also fooled by simulated rain and fog.
You’re technically correct, there is no law prohibiting a current or former president from driving, but there is a policy preventing it and it is enforced by the secret service (who follow them around for the rest of their life). Many former presidents have gone on the record that the lose of their driving privileges really sucks (Bush 43, Clinton, and Obama have all discussed it on camera during various interviews). It’s been a policy since Kennedy was assassinated, lots of other policy changes too, but one was the no driving bit.

And one just about some times they drove anyway:

Policy can be changed. Quite easily.
Especially by the president, when it’s about the president.
Obama, Clinton, others, they don’t really lose their driving privileges. Effectively, they do, sure. But that’s because they’re not utter morons.
Even trump has yet to prove himself that stupid. He probably is that stupid, but he likes the pomp and circumstance, don’t get me wrong.
Other policies include screening people for firearms at rallies- trump over ruled that one, that day, too.
