Again playing devil's advocate (my opinion here is irrelevant), This design follows the intent of all bumper rules. It is well protected from all hits, while still allowing mobility of the trailer. If the bumper rule intent isn't to keep robots protected, then what IS it for? I mean honestly, the rules on bumpers this year are ridiculous to make me reconsider doing next year, as I know they can only follow the same path they've been following the recent years.
