I've been dabbling in working towards getting an auto racing competition license. And there's very little to no complaining about everything people complain about in motocross.
Why is it that most people in motocross want the shortest day possible at the track?
Nobody complains about the long days(12+ hours, with 9-10 of them just sitting in the paddock), a long list of classes you can race in(with some only having 1 or 2 cars and others having 20-30), long drive times to the tracks, etc. Heck lots of people embrace the time they're spending at the track and enjoy the time there after the track goes cold for the night. Having a big pot luck dinner with all the drivers and their family, drinking some adult beverages by someone's rig, and sitting around jibber-jabbering are all part of the experience after driving. Spending the whole weekend at the track is part of the experience, people don't complain about having to be at the track. If everyone could have a three day weekend all the time, everyone would love to be at the track all three days.
Why do people in motocross care so much when costs increase just $5 or $10? It's a few drops in the bucket compared to the costs of a bike, gear, repairs and maintenance, truck (and trailer), etc. Yet some people think sliding it $5 or $10 up or down will either break the sport or help it thrive.
A day or weekend at a road course can vary $50-$200 each day just based on which venue you're at and which organization you're driving with. If track A cost $25 a class to ride and and track B cost $40 a class to ride people would lose their minds. Yet, it's just part of the sport in auto racing. Sure you've got people running on budgets of $200k-$2mil, but a good majority of the people who just come out to drive on a track and have fun aren't rolling in the dough (such as myself). People on a budget save money by the choice of their vehicle they're driving and the modifications done to it, the cost of driving/racing is a fixed cost and it's not worth pouting about. There's people who race maybe half the weekends on the schedule yet they were okay with spending $300 on graphics and $800 on an exhaust, yet they want to be up in arms if it would cost them $5 or $10 more a class to race than they paid last year.
tl;dr - I guess the gist of everything is why do a lot of riders these days want everything to be served to them on a silver platter? Too many people are worried about an hour here or two hours there, $10 here or $20 there, etc. compared to what I've witnessed in driving/racing at road courses where people want to be there and don't mind spending 12 hours at the track with 90% of it just sitting around followed up by camping there or staying at a hotel to wake up and do it all again the next day, or costs varying as much as $400 in just entry fees for a week without even taking into account that they may have drove 12 hours one event compared to just 2 hours for the last.
