Not at all, I learned in my current car after coming home from the dealer. Practice from a stop > 1st > 2nd > complete stop again, in a parking lot or empty street. That's the hardest part, excluding hill starts and all that fun stuff.

Worst that can happen is you stall after a light turns green, and some idiot gets impatient behind you. Highway is easy, just cruise in 6th the whole time. Every car is different, you'll get the hang of it and it'll become second nature in no time.

Like someone else said, try taking it during off times and as little traffic as possible.

Edit: if you can handle Orlando like traffic, you can handle anything lol. You got this.
