Exceptionally bad idea if you ask me.
In addition to the discussion of your gun turning into a missile in an accident, what about all the rest of the crap that ends up in our cars? You don't think that super duper magnet is going to attract all sorts of metal stuff? What happens when you get in the car and drop your keys and "ker-chunk" they attach themselves to the magnet and one ends up through the trigger guard? You reach down there to tug on your keys and "ker-blam". That would suck.
I suppose if you are hell bent on using magnets, you could put a Super Duper 100x Electro Power strength one in your trunk and if you see the bad guy, reach over and turn on the switch and watch while his gun is yanked out of his hands and sticks to the side of your trunk. You could even roll down the road a bit and turn the magnet off and watch as the bad guy runs up to the car to grab his gun. Flip. Turn the switch back on. Ker-chunk. Roll down the road. Flip. Drop. Giggle. Flip. Rinse. Repeat.
