Why do steering wheel locks seem so much less popular now? Same with the reflectors. Nothing’s changed about the best way to keep the car cool while you’re not in it but I almost never see them anymore and I’m in Australia of all places. Those things and to a lesser extent the steering wheel locks were everywhere in the 90s.

Because engine immobilisers are a thing, that’s also why car keys are so expensive. The engine won’t start without the correct key so no need to worry about the wheel.

As for reflectors, the people that use them might just opt for ceramic window tints.

Tinting your windshield is illegal, but I guess you could just use a super clear ceramic film… Except it’s still super expensive and not as effective compared to a simple reflector.
