Ridable entities too heavy on geyser

When a boat, mob, player etc goes on a geyser, they are propelled almost as quick as the geyser eruption and even reach higher height than the top of it + bounce a few times before it stop.
When a player drive a boat or a mob into a geyser, it is slow and you barely reach the top before the geyser eruption ends.

This would be great that it act the same way or almost, rather than feeling you are too heavy when you ride something above them.
