Colorado with 300 sunny days a year is a great place for motorcycles. Most of the year it's warm enough too with somewhat decent clothing and a pair of balls. I'll take the bike any day the road is dry and temps are double digit. But if you really want to increase throughput [FWIW, I don't care that much], just enforce driving on the right lanes when not passing. Then anyone who feels they need to go 15 over the limit can safely do that while at the same time funding the police that the metro is trying so hard to defund. Everyone wins. Bam.
