why's this a Garage post?
Because a lot of people are using these for Motorsport activities. The unit Joe is talking about comes with a suction cup to adhere to the side of your car. If you check their site it even shows the unit in this application.
It's of interest to car guys so... we talk about it in the garage.
Good enough of an idea in this particular garage that someone put together a group buy that turned out to be popular enough to do a couple of times.
props to the OP for mentioning it.
