Yes, but pedestrians and cyclists don't carry number plates do they like legal vehicles. Hence they face higher consequences for being careless and inconsiderate to other road users. Of course we should all be responsible as road users, but that is not the reality. And I would add - pedestrians really are responsible for themselves, their dogs and children first and foremost, not equally with other road users.
Caught many a cyclist on the phone and shouted at them to get off their phones (how much does it cost to get a mount on the handlebars?) and concentrate; get ignored or told to F off. Many of them riding on the pavement at the time and not paying attention, but often they are cycling at low speeds - again that means if they do collide into someone the damage will be minimal v a driver. A numbers game at the end of the day and which can do the most damage.
And all that video shows is the more cars on the roads, the more likely resulting collisions and number of bad drivers to affect other road users. We're getting away from the original point that drivers using their phones cause way more damage and increase risk of accidents that is Fact!
