Drive-by-wire. Scary.

Although I have had a couple of accelerator springs snap over the years and that's been a bit nerve-racking until I realised what it was. Drove 200 miles one night with bailing twine out the window to pull the throttle back!

Unfortunately no get around fix for this fault....if memory serves the one I purchased was French, due to us Brits being unable to produce simple potentiometers anymore.
