Do cyclists make safer drivers? Is there any research that suggests cyclists are safer drivers than drivers who don't cycle? Is there evidence to suggest the opposite?

Please remember this is not a discussion. Please include references to credible research in your answer.
I found a report from the Institute of Advanced Motoring on Cycling Motorists. The vast majority of motorists believe that cyclists do make safer drivers.

Even those motorists who don't cycle believe that cyclists are safer drivers.
