You’re absolutely right.
I was under the assumption that he drove for a while before slumping.
I never even TURN ON my engine when I snooze after leaving a bar a little too buzzed.
It’s NOT often :)
But I have slept 3 or so hours before driving home.
That’s a good way to get killed :)
To do list...STOP SLEEPING IN MY CAR!!
Even if sleeping in the car, one can (and will) still get nailed for DUI if the keys are anywhere near the ignition. It’s a good idea to put the keys in the trunk or some other unreachable spot. Many people have gotten nailed for DUI while sleeping it off in a parking lot with the engine running to stay warm.
