The thing is with a petrol/diesel/lpg/etc powered car you can drive until the tank is nearly empty. Then at a conviniant location along the route stop, fill the fuel tank, go to the toilet, stretch grab a snack etc and be back on the road quickly. Especially if you have more than one person in the car and so can share the burden of driving this allows travelling for long periods with minimal stopped time.
With an electric car so far you can't do that. You have to go out of your way to find a charging station (which are far less common than petrol stations) and then wait a considerable time for your vehicle to charge (how long depends on the particular station but even tesla superchargers which are few and far between apparently take 40 minuites to bring the car to 80% charge)
