80 questions 3 wrong. It is boring and time consuming. Just glad I was able to surf the net while the timer was running and did not need to stay on the page. I browsed a lot of stuff I normally would not have. I identified a possible new job, watched youtube videos and made Google searches of worthless things.
The time saved speeding is usually chewed up when you get the long red lights of Austin so it really is not worth it. Although driving slow (the speed limit) does allow your mind to wander due to the boredom, I do not see this as a safety benefit so I am not really sure which is worse, the speeding or lack of attention due to boredom?

Only one unit left.

I seconded guessed again and changed from 4 feet and gone one wrong.
That makes 3 wrong out of 70. Not bad, but I should not change the answers once I select it.
The answer was.
To lower the probability of a collision, try to maintain at least one car width of space to one side of your vehicle at all times. When possible, it is best to maintain space on both sides of your vehicle. When you must drive through an area with less than one car width of space on the sides, reduce your speed to allow more space to the front.
