The real problem is people for too long have gotten away with bad driving habits because our law enforcement won't enforce the current laws, aside from speeding because it entails a bit of work that which they are supposed to be doing in the fist place... Protect and serve.
That said, if bicyclists in fact have the same privileges as motorized traffic then this shouldn't be an issue at a drive-thru or anywhere else for that matter, because everyone should be looking out for each other. The main issue is people are so caught up in their own little world they rarely see anything other than what is right in front of their noses and oft times not even then because they are distracted with texting, cell phones, makeup, kids, dvds, cds, husbands, wives, drinking, eating, reading books and newspapers...the list is enormous.
If people would just slowdown and figure out how to be courteous to one another again we could be a little safer once more. But honestly, I just don't see that happening anytime soon. The whole of the US is so consumed with profit and themselves there is no room for anything else, let alone one of us on 2 wheels.
I'd love to see bike racks at restaurants, but that means someone needs to pay for that and in this economy where profit is measured by the bean counters, there will be no frivolous expenditures on something only maybe 1/2 of 1% of their clientele would use. Everything is formula based and it is all numbers and the numbers show we do not matter and therefore should be excluded.
Of course we all could just boycott those stores or better yet create a new chain that caters to the environmentally conscious.
Me...I prefer to try to educate those around me in order to effect change. When fuel goes back up to $4.00+ change will happen again. For now I'll patronize the businesses that make accommodations for those like us.
