I'm a driver, not a cyclist, and I'm behind those interventions. People are on the wrong side of the road at a blind corner. If I were turning out, I could end up with someone facing me head on.
On the phone stuff, I support him too, but that law needs a serious tweak to cover emergencies that require less than a 999 call. Stopped at lights, I saw a hit and run, instinctively reached for my phone for a picture, but stopped myself. That's not a net good for society IMO, but it's the law.
