Yeah, most rewinders were horrible… full speed, slamming to a stop only when the tape ran out. A weak tape or tape leader could easily snap, or at minimum pull out of its take up reel… used to hate hearing the sound of a rewinder with a freely spinning motor… meant there was a VHS cassette to fix. (Or Beta-- I have a Beta rewinder sitting around somewhere.)
Marginally improved VHS rewinders were released over the years to include optical sensors that detected clear/translucent tape leader and slowed/stopped the mechanism before yanking the tape apart. Good, except for cassette with no leader, or an opaque leader.
A few also could roughly calculate how close to the start the rewind had gotten by measuring the angular velocity of the take up reel-- the pay out reel would spin backwards at a constant velocity, but as the amount of tape decreased on the take up reel, its velocity increased-- and slow the rewind near the end so the tape wouldn’t snap. Good in theory, but cassettes outside of the T-120/160 length (especially the smaller tapes used for 15/30/60 minute TV specials, or the cheapo LP/SLP bargain tapes) often used larger diameter hubs, which makes such calculations pointless.
