Being a car guy, I can say that properly maintaining sports cars is not cheap.
To the average person who loathes paying $300 for a set of all-season tires every 40K-50K miles, maintenance budgets for a high-performance car can be terrifying.
I had to do long distance commuting in a Lancer Evolution MR for a while. The ultra-grippy tires would last about 10K commuting like a sane person. You could destroy them during a single track day at Watkins Glen. At $1300 a set (shipped, mounted, and balanced). And you still needed to maintain a good set of winter tires despite an absurdly complex torque-vectoring AWD system. And tires were not the biggest items on the maintenance budget.
Even the cheapest sports car money can buy in the US, a Miata, tears through $800 sets of summer tires pretty handily.
People aren't oblivious. Everyone has their priorities. Home. Cars. Technology. Food. Travel. Other hobbies. What some find ridiculous, others find normal, and vice-versa.
