See the much faster leak really messing with the valve stem provides? This would be even faster if snipped rather than just removing the stem core

If you snip the stem off, the tyres will be flat very quickly, they will immediately notice this when pulling away unless they’re completely clueless and ignore the car handling like shit
It could become as normal as talking about dancing:
"I went to dance class last night, only my second week so I still get nervous but it’s good fun and great exercise!
They taught the newer students a new dance and we had to partner up with someone we hadn’t danced with before. I got a lovely older lady and OMG - she was so agile she almost broke MY hip! I’m soo sore but going back tomorrow!"
