To think it's cheaper to pay your car tax?

So, next door neighbour of mine keeps getting his car clamped.
This is now the 3rd time in perhaps 10 months.
It’s clamped due to having no tax.
Each time it is clamped you have to pay £100 (according to the dvla website) and you also need to get tax for it.
He must be getting tax which he pays direct debit for monthly, and then cancels it after a couple of months.
Each time he is paying the release fee of £100.
Surely it would be cheaper for him to actually keep it taxed rather than getting it clamped.
The car is rarely moved, maybe once a month he will drive it. Otherwise it is kept parked on the road.
Also he has a driveway to the side of his house with big 6 foot wooden fences that he could park it behind so the dvla car wouldn’t spot it when it was doing it’s rounds.
Just confused as to why you wouldn’t hide the car behind your 6 foot fences or get it taxed.
It’s probably none of my business, but just musing over how differently other people live.

There was an untaxed, uninsured car with an expired MOT parked opposite my house for weeks, it was there so long that weeds started to grow up the sides of the tyres. It was an old banger and I was sick of the sight of it so I reported it to the DVLA and they came and took it away.

I think that the dvla are quite hot around here as they seem to do a clampdown every 6 weeks or so and clamp about 10 untaxed cars throughout the town in a day.
Not sure why he risks it when he keeps getting clamped and paying £100.
Today will bring the total to £300 within the past 10 months which must be more than a years car tax.
