Should bike helmets be compulsory?

I came across PedalMe cargo bike company last year, and was impressed. It provides a last-mile cargo and passenger ebike service. All of its riders are employed full-time, with pre-scheduled shifts and hourly pay (instead of the per-delivery income in the gig economy model).  Sounds pretty good, hey? But there’s a quirk — their riders are not allowed to wear bike helmets. Pedal Me ecargo bikes carry people and goods across London. Image: Pedal Me According to the company’
