The 5 minute wait was just a "ruse" to disrupt the business model and
ISTM is unlikely to have any effect on drivers congregating "just around
the corner" from major pick up points. It's so short that they would
just wait there for 5 minutes longer.

In that case, the advance booking period needs to be a more-credible 24
hours.

Five minutes is enough - because then there's a more level playing field
between drivers who are parked legally five minutes away, and those who
are parked illegally zero minutes away.

The objective being to disincentivise the zero-minutes-away mob, and
also stop them touting at the kerbside then asking the passenger to call
in the "booking".
