If I was regularly getting shot at while driving my car I'd take action. Bullet proof glass would be a must - sure it is expensive, but I'd pay that price. In fact if this was a regular thing the average car would be built more like a tank - armor, fun flat tires (or metal tracks), probably a scuba type air supply so I can't be gassed out...

But since it isn't a regular thing I don't bother with that. My car wouldn't survive long in a real battle and I'm okay with that as I don't expect to have to drive my car in a real battle.

The warning is out to everything network connected: it is time to invest in the equivalent of armor and bullet proof glass.
