The "1.39" and "40 object" goals are frustratingly hard. I drove what I felt was a great lap and I only clocked in at 32 seconds... which means I have to repeat that two more times? Not likely to happen. As for "40 object", the closest I've gotten to it is 38 and that's after countless tries... sigh.
Funny how you can struggle and be so far away from getting 10 purple orbs but when you do get the achievement, you completely smash the requirement and get like 25+
