GEICO is running an ad for motorcycle insurance that shows a group of 6-8 bikes riding in close formation. I'd estimate that all the bikes are in a space most riders would want to keep for just one bike. Seems counterproductive for an insurance company to show such behavior in an ad.
Last week in the Anchorage area three riders were killed and one injured in an accident. They were riding in what the paper described as a "tandem formation". A car in the opposing lane was stopped to make a left turn across their path. The turning car was rear ended and pushed into the lane of the riders. All four riders hit the car. Had they not been in a tandem formation at least some of the riders would likely have been able to react to the situation and avoided an impact.
GEICO should wise up.
