And i'm sure William would of done the same.... know I would of. Not quite as it happened though, as I believe when he finished the race he didn't seem to care he'd won but was asking about his brother! The bad blood and slaughtering MD got was his post race interview at the NW (I think) where WD beat MD and MD was bitter and aggressive.... not the incident at IOM.
you could here him during his pit stop asking his pit crewif his brother was ok (more shouting at them)
They've both continued in races when the other has crashed, that's just part of racing. It's different during practice. (Edit: If team mates Jimbo & Jace or team mates Wedgie & Tyke stopped every time one of them binned it then they'd never finish a race or practice session ) MD was a knob to William live on TV last year when after a hard fought battle William won at the NW200. In the Superbike race at the TT last year WD crashed out but in the first pit stop all MD was interested in was how his brother was, once he knew WD was OK he then continued and won.
