Sitting around doing nothing. In this context is a more formal way of saying they have not been lazy.

The second one is inviting you to ride with them and commenting you would likely make a good driving companion. It could be friendly or flirting. Not sure what the first one is referring to. It sounds out of context.

Road Test

I have failed the driving skills test twice, even though I had a driver's license in China. The first reason I failed because I was not a skilled driver.  I didn't drive a lot in China or the US . The first time I went for the road test was just one month after I purchased a car, so basically, I didn't practice a lot. The second reason was that I didn't pay enough attention to the nuances between Chineses and American traffic rules. Most of them are similar, but because we don't have stop signs in China I was not really used to it.  The examiner also thought I was too tentative. The third reason, which bedeviled me the most, was that I was anxious and tense.  Many of my friends believed that I should be able to pass the road test, because in daily life I could drive proficiently.  Who would have though my feelings would have been part of the test?  I was so afraid of making mistakes, especially after I failed the first time, that I was even more scared next time.

Tomorrow will be my third time to take a road test. I kind of believe that because by past failures, I now understand how to pass it as long as I don't panic. I have rehearsed the process of the road test several times in my mind to ensure that, even if I am nervous tomorrow, those actions are part of my muscle memory so I can do them in the moment.

Anyway, good luck to me! It's no big deal if I fail, I will keep going!
