In real world of racing, no one is racing only 5 minutes in final. .... it's just plain too fast. Once a driver made mistake, that's it !!! not enough time to regain his position. Is this racing ?
If time is given longer, it will be different story.
Motor burns ? ---> switch to higher turns or use a motor that can.
Overheat tires ? ---> Some GP racers are still racing with rubber tires like Sorex and Take Off, and they race bravely for 45 minutes in final. Do you feel lucky now racing only 5 minutes ? ...... so plz check your car setup. ( edit: BTW..... overheat tires are natural things to happen in real racing, it test your ability to adapt changes
).
IF ROAR wants to attract newbies or keep existing racers, please do something that makes EASIER to drive for regulars and newbies. For examples, tires need new regulation. eg. 26mm width or just switch to foams.
Easier to drive is fun, and it is bigger fun when less tuning equipments & less complicated tuning know hows are involved. I think 'easy' and 'fun' are everyone's self confidence & self motivation to turn up on race events.
Just IMO.....
