Better handling means you don't get so much of an impression of speed. -- Roland Perry

Consider the open road, not a 30mph limit. -- Roland Perry

The answer: All cyclists over 16 to take compulsory test, have compulsory insurance, and be registered. Registration number to be clearly visible on the back of mandatory hi-viz vest. Habitual law breakers' cycles confiscated and crushed. (With thanks to KeithT for the idea)

You are a liar and a fool Clinch: On July 1 2000, the State of Florida exempted adult motorcyclist and moped riders from wearing helmets provided they have medical insurance of $10 000. Monthly time series of motorcycle occupant deaths are examined from 1/1994 to 12/2001. The interrupted time series analysis estimates a 48.6% increase in motorcycle occupant deaths the year after the law change. http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1448295/ ======================================================================== Motorcycle crash-related injuries, fatalities, and fatality rates increased in Kentucky (1998) and Louisiana (1999) following the weakening of their helmet laws covering all riders. http://www.gulfwings.com/MotorcycleHelmetuse.pdf =========================================================================== Arkansas EMS data showed an increase in the number of motorcyclists with head injuries. Texas Trauma Registry data showed that the proportion of cases involving head injury increased and that the cost per case of treating head injury increased substantially after the law change. Arkansas motorcycle operator fatalities increased by 21 percent comparing 1998 with 1996. Texas motorcycle operator fatalities increased by 31 percent comparing 1998 with 1996. http://www.nhtsa.gov/people/injury/pedbimot/motorcycle/EvalofMotor.pdf =============================================================================== An analysis of federal motorcycle crash statistics done by the newspaper Florida Today found "unhelmeted" deaths in Florida rose from 22 in 1998 and 1999, the years before the helmet law repeal, to 250 in 2004, the most recent year of available data. Total motorcycle deaths in the state have increased 67 percent, from 259 in 2000 to 432 in 2004, according to National Highway http://www.cbsnews.com/stories/2006/06/19/health/main1726820.shtml ================================================================================= -- "wearing helmets can sometimes increase the chance of a cyclist being involved in an accident."
