Honestly, I think we know what will happen. The police will either fail to trace the driver, or the registered owner will claim to not know who was driving the car, and if it gets to court, the driver will be of 'good character' who through a momentary lapse of attention thought he'd hit a large pigeon, but didn't stop to check because he was off to visit is mum (bless her) in hospital were she was recovering after a bunion-removal operation. And anyway, I'm sure the cyclist was somehow at fault or came out of nowhere. If, on the off-chance, there's a prosecutorial success then it'll be mere 'careless' driving and a minimal sentence and concurrent driving ban. The driver will back on the road within a year.
But, to be honest, the Met probably couldn't find their own packed lunch in the station fridge, so I wouldn't get your hopes up.
