According to PitPass, Sky have signed a deal with Ted Kravitz as pit lane reporter, Brundle/Crofty to be commentators whilst DC and (thankfully) Jordan stay at the BBC. They also think it’s between Georgie Thompson or Simon Lazenby (currently presents Sky’s ruby coverage) for the program host with Mansell as a pundit. Of course it’s all just rumour at the moment, but it doesn’t sound *too* bad at the moment.
Going back to the OP, I don’t know ANY F1 fans that want Louise Goodman back. She was, and still is, completely useless.
Gravel traps don’t exist on more modern tracks precisely because tar-mac is safer. If a driver goes sideways into a gravel trap and the wheels dig in, the car could flip and injure the driver. tar-mac run-off areas negate this risk.
