Head for a sturdy building if one is nearby. Otherwise, if it is heading toward you and is still in the distance you should try to drive perpendicular or diagonal to its path, depending on what the roads will allow, to get out of its way. If it is getting close get out of the car and lie in a ditch as a last resort.
I would assume that when the tornado hits you are going to be in your car as per the category this was posted under. If you are in your car during a tornado, you should find a ditch and lay in in on your stomach away from your car. If you cannot find a ditch it is suggested to get out of your car and lay under the vehichle in such a manner that if the car would roll either direction the car would not roll on top of you and the car would protect you from debris that is carried by the strong winds.
You could survive, but the car would have to be attached to the ground.
The car would be taken up in the air and destroyed and if your in the car then the chances of living is moderate
Intermittant short?
This is condensation and it is normal for that to happen.
All the lights would go out. Also the radio would turn off. Also you wouldn't get the car started.
It would not be able to move. The push of the engine driving the car forward depends on friction between the tyres and the road. If something else started it moving, the brakes couldn't work to stop it.
what would happen to a car if its reaction force was less than the weight
Yes. You are safer inside a sturdy building than in a car. A tornado does not have to be very strong to lift or roll a car. A car is provably the worst place to be in a tornado after a mobile home.
No. It doesn't take a very strong tornado to pick up or flip a car. If you are in a car and a tornado is coming you should go to the nearest sturdy building or underground shelter. If no shelter is nearby get out of the car and lie in a ditch or depression.
Amphibious car
It depends on the car, but typically it takes a wind of at least 120 mph to lift a car. This is consistent with an EF2 tornado.
