I would gamble that people were drinking and driving hours after the invention of the wheel.

In point of fact people kept alcohol in their cars to be drank while driving back then.

Well, they had self-driving transportation back then so more like drinking and riding.

I am sure there were plenty of sauced stage coach drivers and horsemen.

Your horse knows the way home and will be happy to get your there without help from you (hoping that when you are there you are sober enough to get the harness off so he can finally enjoy a rest at home)

I cannot speak for ze others, but as a creature of ze night… I must confess, I vas, I vas indeed.
