I'd actually be willing to take that bet against the inference. Here's my logic:

The only places that sell individual beers are convenience stores

Some of them are driven too, sure, but lots are also in city areas

Even so, people who only have a few bucks drive to the store where they can buy the beer, and drive home and drink it

If these were common cases, cops would lay in wait and nab them for open container.
