Or get under/behind solid cover. But I wasn't addressing self defense. Somebody has to get the sniper, or the sniper will get more people It doesn't have to be one of his targets. It can be a bystander. Now the Army would just call in an Apache or a Warthog, but that's a little difficult in this scenario, even if you had them on call. Although a Hog in the rearview mirror would tend to make the sniper(s) a tiny bit nervous, don't you think?
