we didnt worry about handling or speedometer for the VI - there are no highways, youre lucky to go over 45 MPH, and mileage is a useless metric.
Of course, here in the states, its totally different. I dont see a real issue with the speedometer reading incorrectly - so long as youre aware of it and compensate accordingly. Handling prowess is another issue, though the actual realized difference is probably quite small.
