I posted this on a similar thread, maybe they should be merged?

Amazon Japan has OBD dongles that lock the doors at a certain speed for around 3000 Yen.

I can't post a link because I am a lurker who has just signed up with a new account.

There are different versions at the bottom.

They price has gone up since last time I looked, or maybe I got mixed up.

 

The link won't display, here it is in plain text for copy and paste.
