100% in favor of the law. Have spent a bunch of time in Cali and my observation was not bikers being reckless going 40 zig zagging thru traffic — it was cars sitting in absolute gridlock not moving for minutes on end, with bikers legally using the available space between cars to make forward progress at reasonable speeds. It’s a great incentive to use a mode of transport that gets great fuel economy and reduces traffic congestion.
People will get wise to this pretty quickly as well. There will be tons of digital signage to educate and this will be heavily covered by all news outlets. “I didn’t know” will not be a good excuse.
IMO a large number of people who drive cars and trucks everywhere should be on bikes. Our roads are too crowded and we can’t afford to maintain them. Most people drive around getting 20mpg with 3+ empty seats in their vehicle. It’s pretty dumb if you really think about it.
