Canada to ban the Flipper Zero to stop surge in car thefts (opens in new tab)

Just anecdotally myself and a few friends used to mod our cars to have 4 to 8 double-pole-double-throw toggle switches under the dash in a metal box bolted to the dash and would secure the wiring harness. Not foolproof but also not trivial to bypass as one has to know which switch goes what direction and it did not cost much. After a while one gets used to fingering the switches into the correct position without much thought. In the incorrect positions the ignition switch is entirely out of the loop. This may be harder to do on newer cars. Maybe a similar yet updated technique could be applied to newer cars?

We wouldn't want to force car makers to hire actual engineers and pay them a living wage to make the cars secure, that would be too much; let's just make crime illegal, that'll solve our problems.

How practical is upping the security short of upping the whole vehicle?
