i dont mean those who race in street with other user on it.. racing in street or track is a dangerous sports.. accident do happens.. in track more preparation like ambulances, safety wears will bring fatality chances down but fatality do happen in tracks.. i mean those underground race scene which are done in place with no other road users around.. not those racing in road where others user around like those rempit fella. ok.. anyway be it on track or not.. make sure enough safety messurement is done before it is too late..
