My local taxi company owner in Bucks used to get fast cars as taxis as he employes 100 plus folk. As a regular I drove his Bentley Continental. 911 Carrera 4s etc.
He had an M5 and shredded the gearbox at Silverstone with onw too many launch controlled starts.
I wonder if the software records and stores how many times you use LC, so the mfr can invoke the small print and wriggle out of a warranty claim ?
I understand Fords line lock and burnout mode can only be used back to back a limited nr of times
