I feel honour-bound to cap this thread. I believe the OP asks a trick question.
The RLJ that causes offence to no-one does not exist.
The question cannot therefore be answered.
Even if the offence was in Ankara and the offended party in Anchorage, offence may be caused merely by the jumping of red lights.
Every RLJ offends someone, even if they weren't present.
I knew i could rely on an ex motorbike courier to come up with some insightful perspective.
I did not wittingly ask a trick question.
As you point out and as Adrian pointed out on the first page of this topic it seems that rljing offends some in its very existence - even without being present.
However i do not recognise the quality of being offending as something that can direct legislation.
In the same way ;
The sale of pig meat offends some.
The exposure of womens bodies in public offends some.
Smoking offends some.
Pornography offends some.
Alcohol offends some.
All legal despite being offensive.
To warrant legislation imho some substantive harm is necessary.
The only valid reason i can comprehend is ; the concept of maintaining the integrity of the "red light means stop" ideal.
This is fundamental to traffic control and should not be undermined.
Consequently i would not advocate rljing being legalised in any circumstances.
But the proliferation of (in both perception and reality) unnecessary traffic lights fuels the undermining of the "red light means stop" ideal (witness rljing) and i would suggest this undermining be remedied by measures like what david k suggests - turning lights of at peak times etc etc anything to alleviate the burden of unnecessary waiting.
