A new weapon has been introduced in the ongoing scooter warfare.

A picture shared to Twitter shows a sticker that reads "clap activated" placed on a Bird scooter. Electric stand-up scooters were notably banned from pedestrian zones along Sixth Street, Red River Street and Rainey Street during Austin's South by Southwest festival.

The less experience scooter-ers among us could possibly read this sticker to mean that one must clap to make the scooter go.

You tricky, tricksters.
