This is a public service announcement.

If you leave your electronic key on the roof of your car, the car will still run, but at some point on your way to work that key will lose it’s battle with friction and find a new resting place. In the road. But you probably won’t notice until you get to Dunkin a few minutes from the office and go inside to get a muffin. That’s when you will realize you can no longer re-start your electronic ignition because you forgot the key on the roof, and it clearly isn’t still on the roof. Luckily, one of your coworkers will be able to pick you up (thanks Rob H) and then your wife will bring you the spare key from home. You will be able to get home and go running after work to look for the missing key. You will probably find it, about a half mile from home just after the first 90 degree turn.

Keys that come of the roof of a car on a road where people drive 50+ mph will get run over. When you find the key, it will be in pieces. On both sides of the road. Spread out over 50 yds. And it won’t work anymore. And that is a $500 mistake, because electronic keys are stupid expensive.
