Charging still takes time, a lot more time than putting the hose in.
With the current lithium-ion technology, high speed charging (over-volting) causes battery degradation due to extra heat. I suppose batteries can be actively cooled to mitigate the process.

But not a lot more time than the average stop already, accounting for human necessities such as stretching, restrooms, food, etc. Full 30 minute or so breaks every 4-6 hours are good for the humans doing the driving, and would reduce some forms of road rage among other psychological benefits.
the amount of power lines needed would be quite astounding; say - 30A at 230V (or 3x 16A for 3 phase) per parking slot.
Also it'd require to hide them under + a way to pay for (but that's trivial compared to the power lines).
Yet, all cars would need standardized plugs too.
It's doable but I'd consider it a futuristic idea.

Again, it doesn't solve the issue with long trips. Last summer my family took a trip through Europe (central/west), often driving 600-800km a day. The range would have not been sufficient, esp. with the high speed German highways.

Not really, because not all parking spots would be charging at full capacity simultaneously. For that reason you can have a lot more charging-enabled parking spots than you have electrical supply for: in the event of unusually high demand, the outlets can throttle themselves to ensure that breakers aren't tripped, etc.

That's where high speed charging comes in. The new charging networks currently being built by Ionity (in Europe) and Electrify America, for example, are capable of 150-350kW charging. At those speeds, you only need one charging stop - of under 30 minutes - to complete that 600-800km day of driving.
We've all got to eat and take toilet breaks, so few people would drive that far without stopping even if they could!
Saving the climate requires quite ambitious plans, but for normal parking spots you don't need fast charging. You need just enough power to recharge typical usage over night.
For long trips Tesla's supercharger network seems to work okay.
