I'd say its even more noticeable in the school holidays how easy walking is with fewer cars on the roads taking kids to school.
Again it comes down to a small shift has a much more noticeable impact on how easy it is to get about.
If you have to wait 10 cars to cross the road normally, if you have 1 less car from that group of 10, then chances are you only have to wait for 5 to 7 cars to be able to cross the road (as there's a good chance you could cross in the gap that car previously occupied rather than having to wait for nine cars to pass to be able to cross).
The same applies for car drivers wishing to exit a side road.
It's why everyone should desire roads to be less well used by cars as however they get about their journeys would be easier.
