It says much for the sensitivity and straightforward commonsense of Ross Brawn, the Mercedes F1 team principal, that he offered Michael Schumacher his profuse apologies for the latest technical glitch which sidelined the seven-times world champion from last weekend's Canadian GP.
As his team-mate Nico Rosberg headed for sixth place and another helping of championship points, Michael’s machine stood silently in the pit lane after an hydraulic failure left its DRS flap on the rear wing jammed open.
Schumacher was correspondingly gracious, saying that he thought the whole team would be understandably frustrated, but that they would be back, fighting fit and ready to go, at Valencia for the next race.
All that was left unaddressed was whether or not DRS was a good idea in the first place.
Publicly, the teams stand forsquare behind its adoption and use. But privately there are two schools of thought; those who believe it is a technically ingenious solution to increase and enhance overtaking.
Others who consider it to be nothing more than over-complicated engineering tomfoolery which generates artificially close racing. With the consequences of a major technical failure obvious to anyone with half a brain will instantly understand.
