cherries way up here

elevator police

went biking out to Shibuya and biking up one of the main Tokyo arteries we biked by a police car with it's cherries flashing BUT! Tokyo police cars have this cool contraption where the lights are on a sort of elevator device where it elevates the lights another 50cm or so above the car roof. I don't understand why this car was using it as it was parked in an uphill spot so anyone coming from behind can quite clearly see but I guess normally it is for better visibility.
