What sort of cars do you drive?

I’ve never had a fuse blow on a car less than 20 years old, and then it was due to shorts due to damaged insulation and bad grounds due to corrosion, which are legit problems that need to be corrected.

Also, unlike breakers, fuses are generally immune to issues with HF interference and the like - they work through basic thermoelectric effects which iron out all but the most extreme issues. If you’re moving multiple amps in a situation described as ‘RF’, or ‘high frequency’ in a DC system that’s not just noise!

That’s a real problem that needs fixing!

Not fixing the underlying problem behind a blown fuse (or constantly tripping breaker) is how your car (or house or whatever) burns to the ground.

Or you have a Lucas, in which case my condolences.

I'll grant you that, I had a lot of beaters. A typical thing was that a lock solenoid pulled too much current in cold weather and consistently blew the central locking fuse.
