Rate the following argument fragment on its writing, argument, and language skills:
Lead: In the 1960's driverless cars seemed more as like a futuristic fantasy rather than reality, but in todays world, they just might be the next big thing. In the late 1950's, General Motors created a concept car that could run on a special test track (Ph. 3). Although this was the first concept of a "smart car", the roads would need an unrealistic upgrade that would cost extremely to much. Today however, we have the technology to make real driverless cars. The toll of human error has been evident in the auto-age as more accidents happen every year.

Score: 2
