Where to practice driving in the Bronx?

My sister in law wants me to show her how to drive. Before driving in the streets I want her to get a feel for the car and get comfortable with it.
I am looking for a good place to practice in the Bronx area with a lot of open space and no traffic passing through (big parking lots that aren’t really used).
I am new to the area so not sure where to take her.
Any suggestions?

Any large parking lot, mall, in the country or store will do but remember that if your sister-in-law is unlicensed then she will be facing a very large fine and you as well can be fined as well if you are caught…
