Hi all, first post and please remember this is only an opinion.
Nascar need to overhaul how they go rain racing or even road racing in general.
The stop at lap 10 to adjust setup because no one had driven in the dry crazy, thats what pitstops are for. If things need to be adjusted do it then, everyone's in the same boat. If you have dry setup data from previous years rely on that.
Now throwing a caution for 5 minutes while the whole field outfits itself for the wet weather isn't the way to go either. Put the decisions into the hands of the crew chief. If the crew chief thinks it is time to put wets on, he should be able to bring his car in and put wet tyres on like any normal pitstop. Have the windscreen wipers and all equipment needed to run in the rain already ON the car in every road course event. All they will have to do is pit for rain tyres which is done in seconds like a normal stop.
Now, the level of cautions for that race was UNACCEPTABLE. If drivers breakdown on the track or are stuck in the kitty fair enough throw a caution pull the car out. Simple. If there is bumpers on the racetrack, get someone to pick it up when the road is clear without the need for a caution.
If there is gravel on the track brought on by another car too bad, these are supposed to be professional race car drivers, they SHOULD be able to cater for changing conditions. Gravel on the track in one area is no cause for a caution. A cutdown tyre with has left small bits of rubber on the track is no cause for a caution on a road course
NASCAR needs to take some notes for their road races from some other series. See how Formula One, DTM and V8 Supercars transitions to wets. All rely heavily on the discression of the teams. Changing conditions should be left with the driver/teams to deal with it not Nascar.
Nascar keep racing in the wet conditions when they happen, it is new to most Nascar drivers and they will only improve with more racing in the wet. Watching the racing at the rear of the field showed the inexperince.
Final point. Nascar have too much control on the outcomes of these races by the use of cautions. Today Ambrose made a mistake and out braked himself into turn 13 and CE was there to sweep up the win. Congrates to CE.
Although, a number of the cautions really weren't needed today and in all probability MA would have bolted down the road with daylight second. The cautions brought MA back to the rest of the runners to make it a much closer finish.
My opinions i have listed above only applys to road course racing, ovals are a different kettle of fish and much more dangerous. I really enjoy watching the high speed oval stuff.
