I know that feeling very well! My first car back in 1978 was a mini! No way I’d ever get into one now 🙂
I tried to get in a Toyota BZ4X SUV, nice and tall, couldn’t even get in under the roof/door to try it!.
Please excuse spelling/typos. Apart from being a clot it turns out I had one on my cerebellum that's now causing various problems!
