Yeah - but that is not the usual modus operandi. These guys were some combination of desperate and dumb. Usually they just slam on the brakes and rely on the car behind rear-ending them. It’s the personal injury claims for whiplash that make the money. Reversing into the car behind is just asking for trouble. They either hadn’t thought their mark here would have such good reflexes or are just not too good at it and misjudged speeds/distances. The other variant seen in UK is to slow down on an on-ramp and the car behind fails to hit them, but cars behind don’t and shove the target into the scammer anyway.
ETA this video is not on an on-ramp but I’ve seen a few that are. Everyone accelerating to motorway speed makes for a more reliable rear-ender.
