The solution to this problem is a vehicle with 600 hp.
You are quite possible on to something...Isnt the solution to every car related question:
"Buy a CL600 Bi-Turbo"
?
I think it is.

Get one of the new Nokia Windows Phones with Nokia Drive. The maps can be downloaded and stored on the phone so no need to use a data connection. Best of both worlds, phone and SatNav![]()
