All I can think about is the time someone slid into my DeLorean at a stoplight. The road was slick & it was dusk. The person fled the scene (naturally the DeLorean was too damned slow to catch up to them). No real damage to my car... the foam behind the bumper did it's job. But if the same thing happened to Jeremiah's car, it could possibly disable his vehicle. Not a knock against him or Eddie, but this solution makes me a tad uneasy.
