Explanation:

Falling VMT would also affect used-car sales and aftermarket parts and service: less driving also means less wear and tear on vehicles, as well as a decline in traffic accidents, cutting into the lucrative collision parts business.

HEYA!!UR ANSWER IS THIS

Explanation:

The spectre of our cities choking with unhealthy air has prompted numerous governments to mandate a transition to electric cars. Their concerns are well founded, even if their proposals fall short of what is needed.

Over the past four decades, cars have become far less polluting. Their fuel efficiency has practically doubled and their tailpipe emissions have been reduced by more than 95%. Yet cities such as London and Paris are still battling smog and pollution. California has for decades demanded the toughest emission standards in the US, and yet Los Angeles heads the list of US cities for bad air quality. Moving to all-electric car fleets will be a positive step, albeit an inadequate measure.

Our urban mobility architecture will have to undergo fundamental change. In Boston, more than 40% of cars in rush-hour traffic have only one occupant. We envelop each occupant, weighing an average of 70-80kg (11-13st), in a package that weighs 20 times their weight to achieve mobility. It takes a lot of energy to move that mass.

Even considering the far greater efficiency of an electric vehicle, zero tailpipe emissions does not mean zero carbon emissions for the travel. Today over 50% of the electricity generated in the UK and over 65% of electricity generated in the US comes from fossil fuels. Our carbon footprint will improve by barely a quarter if we all switch to electric vehicles.

And there are other aspects to be concerned about. We currently demand considerable amounts of valuable urban land for roads. London allocates almost 24% of its land area to roads and supporting infrastructure. In many US cities this can be as high as 40%.

The World Health Organisation has estimated that a city needs to allocate at least nine square metres of green space for each resident. Yet many fast-growing cities around the world are making do with less than two square metres after allocation of ever more precious land to feed the insatiable appetite for roads and parking.
