I live in a rural exurb area. Every spring-fall weekend features parades of supercars of the various supercar clubs. Million dollar plus vehicles. All driving at 60km, driving no differently than the Corolla that accidentally turned into their procession. Because it's all party tricks. These people aren't racing these cars, but are just sitting on potential.
As an aside, I don't remember Tesla ever claiming that their vehicles were the "fastest production car", which is normally a measure of top speed. The Tesla has a positively mediocre top speed compared to supercars, and on any longer run will be demolished. It isn't built for repeat launches, or a quick lap at Nürburgring.
But if you want a very confident merge on the highway, pass on the single lane highway, etc, it can confidently provide what you need.
As an aside, all lithium ion batteries are degraded by high drain (similarly they are degraded by fast charging). Porsche is seeming buying the exact same technology in LG packs. They have identical issues that Tesla does. If you launch a P100d without ludicrous mode you'll do 0-60 in 2.9 seconds.
