That's what happened when I stuffed that V70 on new years day a few
back.
I had plenty of time to stop if I had been handling the modulation,
but the ABS just threw in the towel and allowed the accident to
happen.
I hate lowest-common-denominator engineering.
I guess that's the same as slob-enabled?

Hmmm. Put a switch in the fused line, mount it somewhere
inconspicuously safe...then you can control the ABS.

It's been done by some off-roaders. Some cars the ABS doesn't work
again until you switch the engine off and on.
I think there's a tiny chance that the existence of the switch could
cause the insurance company to deny a claim, since they could claim
the ABS was disabled before an accident, if that accident involved the
inability to stop/swerve.

Wire it up to the 4wd switch... :)

Yup - been there, done that - ABS makes stopping all but impossible on
ice. I hit my brakes in an icy parking lot at a ski area two years
ago. Fully locked up would've stopped the truck in 100 feet.
Instead, my Tundra ABSed itself 1000 feet across the parking lot,
through a stop sign, across a street, down an embankment, across a
stream, and into a group of trees. I might've slowed down 5MPH the
entire time. The kids thought it was hilarious. Took a backhoe to
get me out, and I still have the crunched front end.
