The best automotive investment I ever made was a windshield wiper blade sharpener I bought at a flea market for 10 cents. It's a stamped piece of aluminum with a one-inch groove like two sides of an inside-out triangular file. You get the wiper blade wet (if it's not already) and pull the groove along it 8-10 times. This removes the stiff and cracked edge which is causing the streaking, and exposes a fresh layer of rubber. I get extra years out of blades this way. You could probably duplicate the effect with a small piece of fine sandpaper folded into a V.

IIRC they had a huge publicity campaign, then gradually dropped the speed limit until switchover day, then gradually raised it again. Accidents were indeed low at first, but increased in the following weeks/months as the switch was no longer uppermost in people's minds and they sometimes slipped back into old habits and reflexes.

This 1958 Packard Hawk (I'm pretty sure) lives in the southern part of the Noe Valley neighborhood in San Francisco.

Yeah, but the fake exhausts spoil it for me. It's like putting big slicks on the rear wheels of a front wheel drive car.

The orange NO H2O is based on something close to my first car: a '63 convertible. I can't tell what year this one is, because they've customized the taillights and the grill beneath the rear bumper, which are major clues to the year of a first generation Corvair.

In the industrial paint category DuPont has a couple of brands that include paints with satin finishes: Corlar and Imron.

South. That's San Francisco, but most of what you're seeing is the Presidio, an Army base at the time, now largely a park. The buildings beyond it on the right are in the Richmond and Sunset, largely residential. Downtown and many San Francisco sights (North Beach, Chinatown, cable cars, the Tenderloin, etc.) are two-three miles out of frame on the left.

So from this view, not as much has changed as you might think.

20 years ago a friend of friend worked for the Golden Gate Bridge District, and give me and my girlfriend a private tour. We walked out to the base of the south tower and he opened a battleship-style steel door while other passersby gawked at us. Then up a small elevator to the very top, where there's little walkway. Quite a view and quite a thrill.

Why, thank you very much, but it's mainly because I owned a couple, ages ago. The doors, side trim and windshield frame looked familiar. Both of mine got totaled within weeks of purchase by other drivers running into me. I liked them but they seemed cursed (at least for me), so next was a TR-6.

That last one, the red thing: a heavily-customized Karmann Ghia...? Compare this pick from Canadian Driver:

I'd take the Nash. The Isetta is nice, but I rode in one once and it was rather frightening: imagine sitting on a small sofa going even 40 mph, and all that's in front of you are a couple of tiny bumper guards and what seems like the lower half of a '50s refrigerator door.

Nobody seems to have mentioned the "California roof" option available on the 1995-2000 BMW 318ti:

Some older BMWs had something similar.
