This time our trip to England needs a bit more preparation than usual. In France, a strike by refinery workers has caused many places to run out of petrol, and in London, deluded climate activists are letting the air out of the cars’ tyres. To be on the safe side, we buy two petrol cans for a longer range, adjust the route and have ordered a small tyre pump. Of course, we hope we won’t have to use one or the other.
