You know what, looking carefully at the footage, I think these are indeed tables due to their length. I think these are the standard "trapecveida ātrumvalnis" with 4 m middle and 1+1 m slopes (as opposed to "aploces veida" 2 m ones). I'm just so used to regular humps (and these all feel the same on a bike), I didn't even think about it while trying to find the missing transformer in the meadow ;) You also previously mistagged a couple humps as tables so I wrongly assumed a typo/mistake here. Now I have to think back where else I might have mistagged tables as humps...
