This country was founded by WASPS who spoke English. That's why it became the commonly spoke language just like it is today.

I am less concerned about language skills than driving skills. If everybody drove better,there would be no need to communicate with anybody.
You don't need to know English to drive, you just need to know a few key words (stop, speed limit, caution, etc) and you need to understand the colors (green = go, red = stop, yellow = caution), which are more or less the same everywhere in the world, and the shapes and symbols which can vary country to country but are generally pretty intuitive.
As such, there should be no requirement to speak english to take the driving exam.
Yes, how else are you gonna understand road signs, the legal print on all forms, communicate medical info in case of an accident, ...
If you live in the US, learn English or GTFO! I am an immigrant and came here for the culture, not to push for exceptions because I'm too lazy to learn.
The tests need to be more comprehensive with real understanding of road conditions and driving skills exhibited as a start. Hope this happens in my lifetime.
