What car am I thinking of? Passenger revs/speed readout

[sebhaque]

A post on another thread got me thinking earlier, I seem to recall seeing a car somewhere that had a speed and rpm (not sure on the latter) readout for the passenger. I know the Phantom and such cars have a gauge in the back to tell the passengers how fast they're going (do S-classes and 7ers have said gauges too?), but I'm sure I saw something somewhere about another car (or cars) that had a readout for the passenger. Am I going a bit loopy or can someone confirm whether such a car exists?

ETA - as you can tell, it's been a hard day at work. No beer in the house either and I really cant be bothered to go get some... :[

Ferrari FF?

What on Earth is the point in that?

Hurrah! That's the one. Cheers chap, knew there was some semblance of sense left in my poor old head.

Not sure why you'd need one, mind. That's only going to cause arguments with the missus

I'm not sure anyone riding shotgun in a Ferrari FF should be complaining about someone caning it.

That's a terrible idea that will surely end in divorce.

I was going to say 'every rally car out there'. But it wasn't helpful, clever or funny.

My Mrs would actually explode if any of my cars had that fitted.
