It wasn’t that long ago that there was no speed limit in the pit lane – F1 didn’t introduce one until 1994 – but as crazy as it sounds high-speed incidents were surprisingly rare.
That said, things could still go wrong, like in this Can-Am Challenge race from Watkins Glen in 1980. Geoff Brabham was battling for the lead with John Morton when both came into the pits together. Morton’s stop went fine, but a slow getaway from Brabham meant he was going somewhat slower than his rival. Morton didn’t slow down, went for an impossible gap, and…
Amazingly no-one was hurt because that could have been a lot worse.
