We're not at 54p/kwh....yet....
However, on electric, it is nicer to drive, and it's keeping the towns cleaner (not going to get into where the pollution is generated!).
Also - V60/V90 will achieve more than 25mpg around town I'm sure, so your tipping point may be reduced.

I think this is about spot on. I reckoned, when I was paying about 12.5p per unit that electric driving cost about a quarter the cost of petrol driving, which would give the breakeven at about 50p per unit which is pretty much the same as the above.
