You're correct, Les. 0-60 MPH races are rarely seen or done anymore. I've owned a couple of fast cars in my life - a 1968 Corvette and a 2001 Corvette. I haven't owned a vehicle as fast as either of them since 2014. My MX5 Miata is not fast but it is soooo much fun. But I still yearn for something that is fast, once again. I'm seriously thinking of getting either a Lexus LC500h, LC500, or a Lotus Emira when I start collecting SSI. That's not too far off. 🙂
I have been renting super-fast cars via Turo but each was for 24 hours only. The fastest so far had been a 2019 McLaren 570S Spider. The 2020 Porsche 911 4S Cabriolet was also very fast but it was not as attention-getting as the McLaren.
I don't think I will ever voluntarily sign up to allow my insurance to monitor my driving, even if it means getting a slight discount. But hey, you should consider renting an uncommon sportscar every so often, kind of like a bucket list box to check off. Your insurance company will cover you but they don't need to know when you are renting the car as long as your policy is up to date.
