WLTP is a pretty realistic test though, it should be possible to achieve WLTP range figures.... but like the numbers for ICE vehicles, there still are a lot of factors that can drag it down.... vehicle load (passengers, your fat arse, crap in the boot), temperature, traffic and gradients over the route being just some of them.
The main difference of course between ICE and BEV is that finding a petrol station is relatively easy and quick.... a BEV charging stop is tricky to find, you have to hope that it works when you get there, that someone else isn't using it and even if you have one of the latest 800v charge capable vehicles, the charger you find might only be an old skool 100w charger that takes 24 hours to give you a full charge...
It will get better of course, but we are a long way off nirvana yet even in the UK, let alone trying to drive across Europe.
For now, I'd suggest the main use of BEV is as a local run-around with home charging - and for most people this is probably good enough.... but not mile munchers and not anyone without a driveway... The social divide aspect I find most worrying for the next few years, especially as we can expect aggressive taxation on ICE to force people to give it up.
