Is a Vow the Same as a Pledge?

The UK government have 'vowed' that there will be a 10-fold increase in electric car charging points to 300,000 by 2030 (https://www.theguardian.com/politics/2022/mar/24/uk-government-vows-10-fold-increase-in-electric-car-chargers-by-2030). It's obviously very uncertain whether 'vows' are stronger than 'pledges'! Even if they deliver on the 'vow', there is every probability that charging points will not be prominent in rural areas. The current UK government seem very keen to appeal to well-heeled motorists. A major change in their recent mini-budget was to remove 5p per litre from petrol and diesel duty. Most of that money is actually likely to go to drivers of gas-guzzling SUVs! It would have been rather better (certainly in an environmental sense!) to use any cuts to make public transport cheaper. In some European countries, public transport is actually free!
