You can do 90 on the motorway, in fact you can do pretty much everything with an electric car you can in any fuel driven car. An added bonus with electric cars is that you have maximum torque at any speed so you accelerate like a bat out of hell.
The main problem is range. There is a trade off between weight, volume and range. If you want to travel far, you need a lot of battery capacity and that means adding more weight to the car and sacrificing space to accomodate the extra batteries. At the moment the A123 systems look the most promising (http://www.a123systems.com) but they are still very expensive if you want to use them in a car.
I use these cells in a few of my robots, saving me a large amount of weight and they have a lot of power for such a small cell. When the technology improves, this is a real contender. DeWalt is using them in their 36V cordless powertool range.
