In a Gated Community with Single Family houses, patrolling in a car makes sense as all the residences face the street.

In the Zimmerman case, the Gated Community is comprised of attached Townhouses, with some facing the street and others behind them with a common area in-between.

The only way of patrolling the common area, similar to where the Zimmerman incident took place BTW, was not on the street.

That is a good and valid point and one I had not considered. Also, here we have alleys for service, etc. So it makes sense here to patrol in vehicles. Thank you for pointing this out to me.
