Yep, fuel tax is pretty sensible as it does tax usage, however

It does, in that you use far more petrol when driving in congested
traffic: my Honda Jazz has a mpg meter which although not 100%
accurate shows that I am get around 50mpg driving back from the
all-night Tesco at past midnight when there is next to no traffic,
and only just over half that in stop-start traffic.

But I doubt whether anyone (except perhaps some hauliers) chooses
to travel at a less busy time to save money - time perhaps.
