As usual, Randy puts it into perspective. Don't take it as an insult, as MOST of the time it is ignorance. Back in the old days, the 1950s, no matter whether you had a Healey 100-4, Triumph TR3, or MGA, the girls always asked the same thing, "Is that a Jaguar?" They were not trying to insult you; they just didn't know. The correct answer, by the way, was always, "YES."
And the pecking order for waving, unfortunately, was based on money. The MG waved to the Triumph who waved ato the Healey who waved to the Jaguar. Of course, the wave was always returned until the E-Type crowd showed up. Even if you had a brand spanking new TR3, you still waved to a beat up Healey. But, I didn't mind. It was fun.
At night time, you could even recognize them coming by their headlights and/or parking lights. God, those were the good ol' days. When I got my Miata in 1992, I waved to all Miatas. Maybe 10 percent of them waved back. It was a gender and age problem. 51% of Miata drivers were women, so you could rule them out. Then, most of the male Miata drivers were probably too young to remember roads full of sports cars who waved to each other. My wife used to say, "Why don't you quit waving - you look like a fool." What a shame.
I never had to take any guff off any person driving a BMC car, whether an MG, Healey or XK Jaguar. Because my retort was always the same. "Let's go find a puddle and drive through it! Have you got your distributor towel with you?" And watch the jaws tighten. Actually, the sports car crowd was a pretty good crowd, and most jawing was done in fun.
I used to love to ask the BMC crowd to "please turn your key off. With all that clicking (electric fuel pumps) I can't hear my radio." And metric tools always came in for a few shots, also.
Anybody remember the old Marlboro Race Track, in Maryland?
Wow, I got carried away! Sorry for the digression!
Heard this one about 6 months ago: the three settings on a Lucas headlamp switch: DIM - FLICKER - OFF. You gotta love it.
