An Australian designer came up with a concept for cyclist to brandish a license plate. We cyclists may not be the most stylish lot, but I would have to say that this would be a negative; visually. Not to mention the neck muscle fatigue from wearing this, thing.
If you believe cyclists should be licensed, fine. That’s your opinion and I respect that. Unfortunately this is not the prettiest way of going about it. I’m more for cyclist education than licensing anyway, and I won’t get on my soapbox for that. I’m sure there would be a way to incorporate a license plate on a bicycle/cyclist without making it look, um, huge.
