I mean both of these venues do not have the safety requirements of all the real LSR tracks. Like having to have a chute to go 175, a cage to go over 135, fire surpression systems, door nets, roof rails, head enclosure past 200, and the worn safety equipment rules just to start with. You say you have been racing in Texas since 2003, you must not go to any real LSR tracks or events or you would know what I mean by the lack of safety equipment.
i've only run at Texas, Maxton, Loring, haven't seen "all the real LSR tracks" by which you mean Bonneville events?
Also I ride a bike, so i don't pay detailed attention to cars, but i do see plenty of fire extinguishers, roll cages, parachutes, door nets, head restraints, etc.
I know nothing at all about Miami, but do know that the Texas organizers are VERY diligent about safety.
But no matter how diligent the organizers are, ultimately MY SAFETY IS MY RESPONSIBILITY, and I take that seriously.
