I was one of those "back in the day" guys, my first car was a '66 Sprite in 1975, my second car was a '67 I got a couple years later, followed by a '67 B GT, followed by a '66 TR4a, the 4a became "classic car" instead of a daily driver in 1990 when I got a Mazda RX7.
It was the summers that did me in more than the winters, winter was cold, but in those days I usually wore a tie to work, and sweating in a long sleeve shirt and tie is not much fun.
I had a Sprite for a year or so in the late 90s, it sure felt small in modern traffic, I know there were full size 2 ton american cars aplenty in the 70s, but the cars trucks and SUVs of today are all so much taller than 20 or 30 years ago, look at a modern F150 next to an 80s version. Worry both about being seen and about being run over rather than just run into.
I am less risk averse than many, but using an LBC in this day and age with the large tall vehicles and rampant cel phone talk and texting concerns me a bit. Although I do the sunny day commute to work and drive quite a bit.
