Your drive should never be aiming to show off. Except your own prowess to yourself. (And, arguably, on the test).
The “audience” is a just à townscape of unrelated strangers, and its constantly milling in and out : like at a cabaret bar rather than a sit-down theatre. So, largely ignore their opinion : no critic will be writing about you in the papers tomorrow.
Overall, your car is your “costume” or theatrical prop. Make it part of you, moving elegantly, to enhance how you wish to be seen and understood.
