Tom pushed the unfamiliar gears tentatively, and we shot off into the oppressive heat, leaving them out of sight behind.
At this point, Tom has become familiar about the relationship between Gatsby and Daisy. He shows his frustration of feeling betrayed by releasing his anger on the unfamiliar gas pedals providing a quick get-a-way from the unexpected truth. It’s ironic how Tom reacts considering he too is having an affair.
