I think this comes down to a difference is perspective of trains. Coming from a European perspective when I first read the analogy I was imagining the incredible fast passenger trains over here (~320km/h).
I suspect if you are coming from the perspective of a US rail user then yes, they aren't exactly known for high speed train travel.
320 km/h is not hundreds of miles per hour faster than the top speed of a Tesla, especially one like the Plaid marketed for speed. I don’t give a fuck if you’re from Europe or the US, high speed trains aren’t faster than high speed sports cars. This is from the perspective of someone who’s not an idiot.
