Don’t let your space be violated
We all have a purpose when we enter a parking lot; to find a place to park. There’s really more to it than that. Parking lots are risky places to drive. People are leaving their spots with the hopes of escaping the crowds relatively unscathed. Pedestrians walk between vehicles so they can take less time to either reach the store, or find their vehicle. Because of these issues, we need to have a plan of attack.
If the driver of the little white car behind the SUV suddenly backs out into the aisle just as you approach, they may hit your vehicle or scare you enough that you may swerve into the path of an oncoming 
vehicle. That’s not a good way to start your shopping trip. However, I have a solution that may help.
Although this may seem a little different, it works wonderfully in crowed parking lots. Once you enter the aisle, looking for a place to park, drive down the centre of the aisle. This gives you a better view of empty spaces and will also put you in position to park. If you’re driving too close to the already parked vehicles to your right, you’ll have to swing very wide to be able to park. Most likely you won’t get into the spot safely and will have to adjust your vehicle back and forth until you’re completely in the parking space.
The other advantage of driving down the centre of the parking space is that it gives you more response time if a driver is blindly backing out of their parking space. If you notice someone doing this, you can either brake to slow down, tap the horn to warn them if they’re too close to you; or both. If you were driving too close to the right hand side, another driver backing out blindly from your right may very well hit your vehicle.
The second photo shows the view of driving down the centre of the aisle. There’s plenty of space on both sides of the vehicle, which gives you plenty of time to respond to drivers exiting their parking space, plus it gives you a better view of empty parking spaces.
Driving down the middle of each aisle will give yourself the needed visibility of an open parking space AND to keep away from drivers too close to your right. Stay there until you reach an intersecting aisle at which time you need to move to the right in case someone is turning into your aisle. You would also need to move to the right when you’re approaching an oncoming vehicle.
Space is needed every time we drive, including in a parking lot. Never take it for granted. Just make sure you do something if your space is violated.
