Grand Prix Drivers' Association director Mark Webber has revealed his members' concerns regarding the adoption of Kinetic Energy Recovery Systems for next season in the Formula One World Championship
F1 team BMW Sauber are reportedly yet to identify the cause of an electric shock which struck one of their mechanics during testing in Jerez a few weeks ago, leading to worries that the technology may not be safe.
"There is a report coming from BMW about what happened there, but the rumour is they haven't a clue why it happened," Webber (pictured) told Autosport.
"They have no idea - and that is a worry. You only need to think about what would happen if someone gets shocked into the fast lane of the pitlane."
Webber explained the fears further via a real-life comparison - with an aeroplane disaster.
"It is like a plane crash when you don't get the evidence," he said.
However the teams seem less concerned that they will have the technology in place for 2009, fully tested and harmless.
"It is flavour of the month, but the simple fact is that teams will get on top of it," Force India chief technical officer Mike Gascoyne said.
"As soon as one person does, the nature of Formula One means everyone else has to.
"I'm sure [BMW] are working to understand [what happened], but it should be straightforward.
"Certainly the electronic KERS we're looking at is a fully sealed unit. All the high-tension cables are within a sealed unit. It's difficult to see how you can have a problem."
