Your opinions please, about collision switch. I am just now replacing the electric pump in a new-to-me 37 Streetrod. No mechanical pump. Going to add a low-oil-pressure cut-off switch. (a Holley part, open at 5 psi)

Do you think I should have a collision switch too? I guess it wouldn't hurt; belt and suspenders. But as I think about the risk being protected against, it would have to be a collision hard enough to rupture a fuel line, I'm unconscious so can't turn off the key, but still the engine keeps running a while on the gas in the carb. Whats the odds of all that? Maybe if I got rear-ended hard. Are there other scenarios, other risks I'm not thinking of? Are there other benefits to a collision switch?
