How many other crimes are directly defined with a time-sensitive impairment?

If they allowed you to both call a lawyer and wait for them to arrive you could arrange for your lawyer to be a) 2+hrs away, b)alseep or c)any other time delaying tactic.

I agree I don’t like the status quo, but if you have a reasonable alternative that still allows them to catch people who are drunk driving, I’m all ears.
