While more people opt for travel by car and private transport, the number of passengers that trains and buses can carry has also been reduced to meet social distancing guidelines. This means that people from different households must keep one to two metres apart. So, once a seat is taken, surrounding seats must be left empty.
This has had a profound effect on the climate impact of train and car travel. When running at normal capacity, public transport is more environmentally friendly than travelling by car. Although a train or bus can produce more C0₂ than a car, they transport far more people, so emissions per person are lower overall.
But under social distancing conditions, and assuming that any unfilled seats correspond to a commuter driving to work instead, diesel-powered public transport produces more C0₂ emissions per passenger than a small car.
Can passengers be seated so public transportation can be more efficient than cars while maintaining social distancing?

What virus is going to do that? Covid hasn't come within three orders of magnitude of reducing population by 1%.
Who would these "friends" be? Nobody has shown that a man-made disease has made it into the wild yet.
Are not more environmentally friendly than what? What better configurations of 7.5 billion people are there?

Math error. Global deaths from covid could be underreported too.

The secondary damage (economic etc) could cause stuff like famines, major civil unrest or even wars. Fewer people are immune to no food for 1 month...
But there will likely still be billions of people around - we've already figured out how to produce enough food for billions and we don't need high levels of tech to do so. Most of the farmers in India helping to feed their 1+ billion people aren't using robotic combine harvesters.

"Likely" by what standard of evidence? It's interesting how much terrible advice has been given here on SN about this subject by ACs. First, smoking was alleged to increase resistance to COVID. Then it was that masks don't prevent the spread of COVID while simultaneously ignoring how masks do that. Today it's this crap and the claim that wearing masks makes one susceptible to covid (in other words, it's somehow better to get repeated COVID infections than not).
What secondary damage?
