In my car the UI just freezes until the headunit restarts 1-2 minutes later. A few years ago I rode with a friend and he'd have to turn ignition off and on again to restart the headunit. That's rather annoying while cruising on the highway. The madman still did it - a bit dangerous because you lose power steering and the brake booster without the engine running.
