Diesel vehicles are 11% of vehicle miles traveled in the US, and around 60 people died in diesel vehicle fires last year (12% of vehicle fire fatalities). So they seem to be as dangerous as gasoline vehicles. This is probably because while diesel is more difficult to ignite than gasoline, diesel vehicles tend to have larger fuel tanks, so the harm caused by a diesel fire tends to be greater.
