Yeah I get it, but checking behind my car and looking around for kids always worked. Yeah I know, things can change in 5 seconds. Okay, what about seat warmers? Why do we even need them? Just a fluff. Do car mfrs. have to recall cars if there's a problem with them? Does a warning light appear on the dash for something that trivial and unnecessary? Does it affect the computer? It shouldn't, but who knows these days. I wish I had my 67 Mustang. No nonsense, I could do any repair on it myself, no engine or oil/maintenance required lights, no emission crap. My 1985 Ford had a fender-mounted control module (Standard ignition part # was LX203) that I had to change once or twice in 15 years and that was it! No computer analysis was needed. If the car didn't start it was the coil, module or fuel pump. All easily replaced. Oh well.
