I'm not criticising anyone. Drivers making hay while the sun shines is perfectly logical. Derek got a decent campaign going and, yes, I was hopeful that he might have attracted more support, particularly from the other drivers unions but as much as Derek might sing and dance, money talks. I've no problem with fixed fares. The taximeter is a relatively new introduction to the trade where I work and north county folk do like to know what a taxi is going to cost hence they are more likely to use taxis with that information up front. Uber's current rates are set as close to the meter as makes no difference in my experience.
I know your preference is to pay higher commission to enable the various platforms compete on price. That, to me, makes no sense simply because the VATman gets a significant cut of what drivers pay. However, I suspect that is the model they will all follow as and when they want profit. Interestingly, they focus driver earnings data on fares after commission whereas fares before commission, being the higher numbers, would be logical point of focus. The reason for that is that commission will be the variable with rates set dynamically in the fullness of time.
