The moment Lex drove through the power up, a button on his golf that was previously gray turned blue. Lex clicked his tongue in annoyance, but didn't focus on it for too long. He, like every other participant in the race, had memorized all the available power ups and how to identify them. There were three buttons on the golf cart, each of which would turn a certain color based on the power up he received.
Once he used up a power up, the button would once again turn gray, meaning he could hoard up to 3 power ups at a time at most. The blue power up wasn't actually bad, but it was designed for someone who was trailing in the race. It would give the racer a temporary speed boost, its speed and duration based on how far behind he was.
Although Lex could not tell for certain, since the entire track was not visible to him, he was fairly certain he was in the top 10, so the boost would be short and tame. But beggars couldn't be choosers.
