Just bought my first American car (not my fault)
It locks all the doors when you go above 10mph and they stay locked even when you stop and turn the engine off. The drivers door opens but you have to press a button to release the passengers, I keep walking off to see my wife fuming at being kept prisoner.
And for some reason I don't understand, the remote unlock doesn't do the driver's door - you have to use the key to get in.
If I wasn't a programmer I would RTFM and find out how to stop it.
