Good way of putting it, but imo it's not going to happen in our lifetime in this country.
This not in the government plans, not what the general public sets its priorities on.
Pat 5mph sprinting at the lights, keeping up with traffic a' la Cyclecraft text book of national cycling standard is not compatible, even impossible to achieve.
Heck, the likes of me are harassed by other, faster cyclist, never mind motorized traffic.
Separate infrastructures would help to no end, but the faster cyclists (not as fast as cars though, so are getting harassed in their cycling too) don't want these infrastructures.
The government does not want to spend money on them either, nay, let's rather equip the cyclists to go into daily battle with motorized traffic, get them some training, drivers will understand why that cyclist rides in the middle of the road.
Meanwhile, the general public, cyclists (me too!) included, expect their Tesco, Amazon, Parcelforce deliveries to arrive promptly and cheaply.
The reality is what it is, us less skilled cyclist must, in the current state of affairs, stay clear of large vehicles and avoid fast flowing traffic.
A bit ot, not relevant to tipper trucks: I believe that aggressive driving could be curbed by social awareness, it should be made unacceptable, like drink driving.
