The financial, spatial and carbon economy of motorised private transport is inefficient, including its infrastructure. Opportunity costs of missing climate action due to economical reliance on private transport, spatial constraints of land use for traffic and inefficient housing (private transport induced sprawl) are just two examples for that.

Climate change fuels flooding frequency and severity, so fueling climate change with fossil fuelled private transport is irresponsible.

Reduced inpacts of climate change but more importantly better urban design. Long, straight, impermeable roads guide water wherever it wants to go with little resistance or slow downs. Cities can be built to be more permeable to handle water better, they can also implement stomwater retention and detention ponds.

Many cities currently waste lots of space on asphalt for cars. We could build transit with permeable surfaces (such as grassy tram lines or cycle lanes designed from permeable materials). We could build less parking lots and save that space for stormwater ponds.
