I have had many Renaults, and I can affirm that the newest ones have the speedo on the right and the older ones have the rpm on the right. Maybe in order to the co-driver can't see the speed?
The position really don't mind, is the same.
Scawen: You mentioned a 'dashboard editing controls'. Could you explain which improves will bring this? Could be the dashboard editable by the user, like the Analog Gauges, but moving with the car, and hidded by the steering wheel?
