A car is never going to be a secure spot, but since yours is a coupe, it's not too bad.

You can get a small "gun safe" that comes with a steel cable that would slip under a seat. The cable then goes around something like a seat rail or mount. It'll slow folks down unless they know it's there and are looking for it. No matter what you do with a vehicle, it's always possible for them to steal the whole vehicle.

You may have just been wanting to let the guy know that he was running his brights, or you may have been annoyed and trying to convey that. Either way, this guy seems to have been in a mood and not liked it. You may want to avoid the light flashing in the future.

People are crazy. I assume you saw the recent thread where 2 different sets of numbnuts fired their gun through the windows of their own vehicle.
