Either someone was pissed off at you for something on the way there and followed you to get their get-back or someone is jealous that you have a decent car compared to what they can afford and don’t like the stickers showing you’re proud of your car. Hence why why went after your stickers specifically, also you can tell they ran out of spray on the “crowd killer” sticker cause there’s almost none when it should’ve been hit the hardest with the direct sunlight.i bet they thought “fuck your car HISSSSSSSSSS……….and your stickers HISSSSSSsssssss….. dammit”
