What? You're doing it again!
I mentioned once that if an RX8 is achieving 20MPG, then what is a 330 going to be doing under the same conditions? I estimated 22-25MPG, and then asked you what you got in your 530, but you didn't respond.
It is a simple fix to simply not park in front of people. This is something that will be a problem for some people, but not for most, IMO.
