MILTON KEYNES: Formula One champion Sebastian Vettel says motor racing should try to improve safety after the death of IndyCar driver Dan Wheldon, although drivers accept the dangers involved.

The Red Bull driver calls Wheldon's death a “big loss” but says risks can not be avoided.

The German says “we are ready to take that into account because we love racing and we love motor sports and it is dangerous.”

The last F1 driver killed on the track was Ayrton Senna in 1994.

Vettel says some claim F1 has become “too safe” but stresses that Wheldon's death shows racing should never stop trying to improve safety.

The 33-year-old Wheldon, a two-time Indianapolis 500 winner, died Sunday in a fiery wreck at an IndyCar race in Las Vegas.

Vettel returned to the Red Bull team's factory Wednesday for the first time since winning his second straight F1 title.
