Wow, are the cars tornado chasers like those in the movie Twister? I'd love to read more about those, but really cool to see how all these are moving. Way more things out there then I thought.
The cars on the map are the locations of people who are hunting for balloons after they have fallen back to earth. SondeHub's "chase mode" allows you to announce your position so that others will know you're in the area and will possibly soon collect a nearby balloon.
Depends on the level of chaser. One professional that I know has reinforced his windows to survive hail and other potential debris. He's now to the point where he has sponsors, so his car has vinyl wraps and damn near looks like it would be at home at a NASCAR event.
