So, it's a good thing wobblers ride cruisers... One comment- and this is becoming a theme with me: FMVSS 218, which defines the DOT helmet standard, calls for the antiquated hard shell / Styrofoam liner. You can't build a DOT approved helmet without including those two elements, because that's the definition of 'DOT approved helmet'. See also LED turn signals, which can be smaller and yet brighter and more visible than incandescent... but not legal, because FMVSS 108 specifies a minimum amount of "equivalent lens area" of 3.5 square inches, written into law to accomodate crap-tastic motocycle electrical systems. The rules are clearly not keeping up with technology; I pray for the day they stop legislating to the current technology and instead legislate the desired effect. Not holding my breath, though.
