Every kilometre you drive, you hand the state some tax and impose
some cost on everyone else. The two rarely match — this shows how much of your
road use you actually cover.

The twist
Going electric covers less, not more
Switch to electric. The cost side barely moves — crashes
and congestion are most of it, and an EV imposes both. The payment side
collapses: almost no fuel tax, plus a purchase grant. So the public ends up
covering a bigger share of an EV's footprint than a petrol car's.
That's a deliberate decarbonisation subsidy, not a free lunch — worth knowing.
How to read this
Per kilometre, solo. Costs are the handbook's per-passenger-km
figures treated as per-km for a single rider — your real footprint if you
drive alone. Carpooling lowers the per-person cost.
Congestion is a band, never a point. It's the most place- and
time-specific cost; the selector swings it from open road to rush-hour core.
Two-wheelers filter traffic, so theirs stays zero — which is where a
scooter quietly wins a dense city.
A scooter isn't a free angel. It still carries real crash cost —
though most of that risk falls on the rider, and much of the rest comes from
car drivers.
This is a model to argue with. Every rate above is editable.
