Why not just start an alarm 10 seconds after the key is out of range? Or automatically shut off the engine if the key has been out of range for more than 5 minutes. That still prevents accidents while driving (there were cases where children threw keys out of the window) but should be safe otherwise. And programming that timer shouldn't be a lot of work. The detection already exists anyway.
- sokoloff 8y agoThe cars need to work when the key battery is dead. My LEAF has an inductive charger near the start button that allows you to "charge" the key just enough to do the security exchange and then start it. It's quite possible, even likely, that more than 2 people per year would die from environmental exposure if we programmed cars to not work if the key battery dies (as a proxy for "key out of range"). (Drive out to a deserted location, shut down, enjoy the day, get back in to find a dead car key battery. You want to be able to get home rather than stay at the trailhead.)
- dx034 8y agoAn alarm would still be fine though? Maybe with an option to deactivate it. I'd want to know when the key gets removed from the car, not having any notification appears wrong.
- sokoloff 8y agoMine gives an alarm when you take the key out of the car already. "key not detected" or some such.
- pwinnski 8y agoMy car displays something on the screen, but I don't recall it making a noise. I've left the car running while stepping into a store because someone was in the passenger seat. If I get too far, my bluetooth music stops, but the air-conditioning keeps going without the key.
- rpcope1 8y agoAll of this still sounds unnecessarily complicated and Rube Goldbergian in comparison to just using a regular physical key.
