The postings on leaving a good amount of room in front of your car are great I teach it always..!
( You must also be on the look out for the car crash and grabs...there seems to be an increase of bogus bumps from behind at stop sighns and traffic lights, they always have witnesses in their car...and when you get out or roll down window...gotcha.!)
I teach my friends and family to drive directly to a well lighted parking lot or to a police station.
As to my TIP for you all:
When using an ATM at a Bank location, adjust your rearview mirror to see behind you in the drive up slot...aim it back more and slightly down to catch the SNATCH & GRABS who just about Belly crawl up to your side waiting for the money to spit out.
When using the walk up, try not to use the ones with the vestibule rooms in non viewable locations (Ie...in back of banks), even though you pull the door shut, you are penning yourself in for the hoodlum to wait for you to exit, at his mercy.
Instead I prefer the open faced ones on the front of the bank close to the road were I am more easily visible and my avenues for escape are greater.
And finaly when confronted by a would-be robber the commonly taught practice is to throw your wallet or purse on the ground away from you and flee the area.
The idea that they will go for the money and not bother with you.
I teach that this is OK , but not my prefered aproach .
Often as not they have acomplices who are just dieing to pistol wip you or restrain you from fleaing.
I teach to be aware of were exactly the roof is of the building you are standing next too, and if threatend or your instincts go into overdrive, throw your wallet and or pocket book on the roof.
The look on the bad guys face as your money and credit cards are out of his reach and you are screaming your head off, will get him moving out in a hurry.
Then simply call for the police, they will assist you in the recovery of your belongings , and will be put on notice of your close call. They will be forced to patrol the area more dilegently, and have them stupid shrubs moved or trimmed so as not to provide lurking places.
( The above mentioned technique was taught to my own mother of 74 yrs. she executed it with style, and when the LEO officers stopped howling in delight they asked if MOM, ever met me.
She told them her name, and said YES the very first minute I was born...
