Hello @demaniak apologies, forgot to reply to this thread. The intended behavior for a cyber truck being dropped on a player at the beginning of the round is for the cyber truck to be ignored by that player (because the start block of a round ignores everything as interactions regarding that block are considered in the previous round). As such the behavior described where player 2 ignored the truck and then player 1 who was behind travelled into the cyber truck is the correct behaviour.
The cyber truck hitting a player in their starting block is thus a bug that we resolved, it is unclear why you experienced a unique case where the player ignored the cyber truck even though that bug fix has not been released.
I hope this clarifies the question. If not please let me know
