If you dig a hole 3 blocks deep, add 3 layers of snow and then drop in 4 minecarts (Type shouldn't matter), the hitboxes work out just barely so that they do not trigger the tripwire but stop other minecarts dead in their track without any bounce. Those minecarts however DO trigger the tripwire with some sub-pixel tomfoolery.
What is this useful for? No idea, I was trieng to find an alternative to detector rails. I needet a minecart ontop of both a detector rail and a powered rail, so I can have it on standby on the detector rail and once the attached repeater reads sufficient inventory, the powered rail sends it off to processing.
But obviously, having a detector rail touching a powerd rail isn't ideal if you wanna trigger said powered rail at a time of your choosing rather than yes. Have not found a sollution yet, but I'll try finding a setup that essencially let's the cart bounce over the one below it like a rock skipping over water. Not super confidant-

This goes on to the “very specific setup with maybe an extremely specific niche application” list
Update, queue ‘That was easy’ sound effect. 4 blocks deep, 5 carts and 5 layers of snow. I expected this to take a LOT longer.
I the best solution for your problem might be to swap the detector rail for a powered rail.
A way this is commonly done is also just having the minecart go up a tiny detector rail slope and using a fence gate to trap it there until you want to release it.
You can push a block into the carts to get a kinked rail going towards the tripwire, then a cart will drop 1 item, trigger the tripwire and then go back down the kinked rail. This will be very useful for a problem that has not been discovered yet.
