Always waved in the SAAB (years ago, with a mid seventies 99 EMS).

Always waved in the Morgan.

Always waved on the BMW bike, but only to other BMW bikes. If Hondas/etc waved, I waved back. Harleys never waved, lol.

Can't imagine waving in a BMW vehicle today, there are at least five X5s in my block, as well as a sprinkling of 3/5/6/7 series.
