I can start my 2007 Saab 9-3 Aero wagon with my thumb.

If I put the key next to the ignition switch between the seats the switch will sense the key and unlock the steering wheel. Then I can stick my thumb in the switch and start the car.

When I first got the car I asked if the lights could be programmed to run with only the parking lights and fog lights on. The service department at my Saab dealer said no. A few years later after a battery replacement I can have only my fog lights and parking lights on.

If I have to disconnect the battery on the battery for more than 10 minutes the front windows “forget” for a week or so that they have a one-touch up function. They eventually remember.
