smart phone, stupid drivers
As I rode past a line of slow-moving cars today, I counted 8 drivers using their phone (out of 46 cars). The laws aren't working. We seem to be stuck with this sickness: people in control of tonnes of steel lost in distraction.
It's a pity the car manufacturers don't use the electrified steel cages they sell as Faraday cages to prevent cell use when the car is moving.
