[Star Wars] In The Last Jedi, why did the rebels even use those weird sand rider vehicles? They weren’t capable of disabling the Walkers right? So why even jump in them?

just to buy time?  

in empire the rebels used those small snow craft with the Cables to trip walkers

but the sand vehicles from TLJ didn’t seem to have any ability to disable a single walker

like it could be 20 rebel vehicles vs 1 Walker and the walker would win...

When they were gearing up the sand skimmers, the plan was to hunker down, call in the cavalry (all the assorted allies of Leia and the Resistance who they were trying to contact), and then stall for time until backup arrives. The little craft weren't qualified to hurt a walker, *but the Walker commanders don't know that*. They need to consider the prospect that the small ships have upgraded guns, or missiles salvaged from the Resistance's Starfighter arsenal, or are converted to suicide bombs, and can't afford to just walk past them.

But then the cavalry tells Leia to go fuck herself. Now, it's no longer about stalling for a specific goal. It's just desperation, hoping they can buy another few seconds in death for a salvation that may not come.
