Apparently our readers are purists, preferring a super car with a 5-speed manual and without traction control to the high-tech gew-gaws of the 430 Scuderia.

It's slightly less effective than a manual transmission, but remember you only need to use the stall recovery technique on really steep hills where traction is compromised.

At present, traction motor testing devices in most railway factories and segments adopt handwork control, manual reading instruments and recording data.
