You and your two best mates are driving around in your crappy little Lada whose brakes have always been fussy. And one day they completely shit the bed and you’re left with no brakes in traffic. What then?
Well, they’re your best mates for a reason, right? So, of course, they act as a set of human brakes for you while you limp your crappy little Lada to a repair shop. No one could ask for better friends.
What I just wrote is all totally hypothetical and should never happen to anyone ever. Do not act as a set of human brakes for a car. That is very dangerous. It’s better to bump cars than to potentially get your body caught between two of them. There are bumpers and crumple zones for this very reason.
