According to GPDA (Grand Prix Drivers' Association) director
Mark Webber, Formula 1 drivers' concerns about the safety of Kinetic Energy Recovery Systems
(KERS) have increased because team BMW-Sauber have not yet found out what caused their electric shock incident in Jerez.
Webber said to
Autosport.com that the
KERS safety debate will become much bigger if BMW-Sauber cannot get to the bottom of what it was that caused one of their mechanics to suffer an electric shock during testing.
Drivers at the Hungarian Grand Prix discussed the matter, as they await the results of BMW-Sauber's investigations into the matter.
On the other hand, all the teams involved in the sport are confident they will eventually get KERS completely safe.
"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," said Force India's chief technical officer Mike Gascoyne.
On top of the safety issues, some teams are also worried about the costs involved in developing KERS - with rumours that some manufacturers have set aside as much as 70$ million in bringing on the technology over the next few years.
