“ Thoughts -
1. does Potters Bar still have 1 hr free parking?
2. if its easy to pay, I'm more likely to be willing to pay
3. I don't usually carry my mobile phone
4. That stupid notice is not designed for people with bifocals
5. Normal people can usually remember a number up to about 5 digits long, not longer.
6. Presumably 33 London boroughs have 33 systems, likely all different
7. My bike looks a better solution every day ”
