Well that's bollocks. All the lazy twats will decide its reasonable to drive.
Feasible, appropriate and reasonable are not measurable things, so how on earth could someone get those stats?
I’ll list a few reasons why someone who is not using their motor vehicle for work purposes may need to complete their supposedly unnecessary journey using a motor vehicle:
1. Disability is not always visible nor is it always recorded as such in the eyes of the authorities so in order to go out and live life like an independent person a motor vehicle may be the only way someone can get somewhere otherwise they may be forced to stay home and lead less of an independent and isolating life
2. Illness may make it difficult for someone to be able to walk or cycle or use public transport and a motor vehicle may be the only way they can get around
3. Infirmity may make it difficult for someone to be able walk or cycle or use public transport and a motor vehicle may be the only way they can get around
4. Phobia may make it difficult for someone to be able to walk or cycle or use public transport and a motor vehicle may be the only way they can get around
5. Any number of medical conditions may make it difficult to walk or cycle or use public transport and a motor vehicle may be the only way they can get around
6. Covid/viruses - some people may still be shielding and may need to stay off public transport for health reasons
7. Late night shift workers - public transport does not run everywhere 24/7 so a motor vehicle may be the only way to get home or get to work for some in a reasonable timeframe
8. Long circuitous routes are not served well by public transport - some journeys may require you to head into Central London and switch to another major station to then go back out when a direct route using a motor vehicle would save time which could facilitate more family time at home
9. Safety, many people, especially women do not want to use public transport late at night on their own and would prefer to take a cab or drive and there are numerous well known cases of women being harassed, attacked or sexually assaulted and even murdered when out walking on their own
10. Cab fares are not cheap these days and you can't always get a cab when you need one and if someone regularly needs to get to/from work at an unsociable time the cost of a long cab ride may well be more than the cost of running a car - the minimum fare for even the shortest cab ride is close to £10 - if you had to get a cab twice a day for work purposes at a cost of £7.50 and you worked between 200 and 250 days a year you would spend between £3k to £3750 a year and running a car would probably be cheaper
11 Antisocial behaviour / crime / violence / safety on the street and on public transport is often a problem especially late at night that many people would not want to encounter such issues
12. Safety issues riding a bike may put off some people using a bike to complete short journeys
13. Family or friends giving someone seen as vulnerable such as a child or OAP a lift home to ensure they get home
14. Taking large items short distances such as personal possessions or or shopping may not be possible on foot or using a bike or on public transport
I'm sure I could think of more scenarios but all of these could be said to be valid reasons why someone would not be unreasonable in completing a journey using a motor vehicle
