I also thought that was a totally bizarre feature.

The only use I can think of is collecting the data and using it to determine and suggest enjoyable routes. So the Sat Nav can suggest an alternative route that might be slower but is a lot more fun to drive.

It's a concept vehicle. They're always full of crazy, stupid crap that would make actually driving the vehicle awful.

Yeah, that was seriously weird. No one needs an emoticon to tell himself his own mood.

It could be useful for surveillance purposes though..
