>But if you're going to bring that up anyway, how are people supposed to get their car home from the bar in a place where the government hates public transport?

An anecdote related to me by a former (Florida) county sheriff's deputy answers that question:

Many police will stake out bars around closing time, awaiting the intoxicated to get behind the wheel so they can be stopped, breathalyzed and arrested.

However, patrons were aware of this and the deputy saw a patron leave, stumbling, drop their car keys several times, then get into their car and drive away.

When stopping said individual, the breathalyzer and field sobriety test showed the driver to be stone cold sober. As such, the deputy sent the driver on their way.

Returning to the bar parking lot, he found that all the other patrons had departed while he was wasting his time on the one sober person -- dubbed the "designated decoy."

I'm sure other variations are and have been in use in the US for a long time -- since most places don't have public transportation or reliable taxis.

The "cars first, public transit last, if at all" culture in most of the US makes the likelihood of DUI/DWI and crashes/injuries/fatalities much, much worse.
