Agree , i have been wearing neck braces ,for years , mostly on motorbikes , ofrroad and rally , first time , felt ristricted in movement , and the felt i could not move my head in a good way , just kept using it , and i think it saved me from ending up in a wheelchair .
After a while i got so used to it , i did not bother me at all , would never race without one , same for a helmet .
The car i would not think about it , an go for it , looks like a blast to drive , just start of slow , and know your limits , no big deal , you do not have to be the fasted guy out there , just enjoy it .
