I have passed my theory test in England and need to get mobile asap in Spain, not sure if moped is quicker and or cheaper. Also do i need to retake my theory test?

I am a 19 year old female college student attending Arizona State University and considering getting a Vespa /moped in lieu of a used car. It's certainly less expensive in cost, maintenance, insurance, gas, etc, plus it's better for the environment. Before I decide on that route, I would like to hear if anyone has experience riding a moped in a city / campus environment. I will mainly be using it for short distances - mostly around town (errands, groceries, etc.). What are the pros and cons? Thanks.

I live in Vietnam and drive a Honda Wave everywhere I go. If I ever move back to the US I'd like to look into getting a motorcycle license. I'm still trying to work out the official differences between a moped and a motorcycle but I also wonder if there are major differences in the way a (non-automatic) moped and a big bad motorcycle are driven.

I'm looking at getting a 49cc moped so I don't have to get a motorcycle license. I want to know if anyone has a moped and what the insurance cost is.
