So you're saying we just need to electrify our cars but cars are fine otherwise?

What I'm trying to say is that is that the switch to BEV's may have a lot of additional leverage, in the sense that you're not trading electric miles for gas/diesel miles on a one to one basis. I'm suggesting that when you no longer have to take deep breaths of toxic haze to ride a bicycle people will do it a lot more, and you will automatically see a substantial number of trips which are now car trips shifting over to biking or walking. An all BEV fleet would make bicycling an order of magnitude more fun and healthy.

I'll tell you this, when I choose to bike or not bike, it's not because of car exhaust that I feel unsafe. It's drivers not viewing me as human and engineers thinking drivers will respect unprotected bike lakes.

Exactly the same reason I don’t bike the 1.7 mile trip to my bus. The only route is dangerous. Part of it is 6(!) lanes and I’ve seen drivers cutting off other drivers as they make last minute decisions. I wouldn’t stand a chance.

Those are very real concerns, and they also need to be addressed, but the bad effects of breathing the exhaust from cars trucks and buses are real and well documented. When you guys hit a cloud of stinky exhaust do you hold your breath or just breathe it in? When I get a whiff of diesel I just try to hold my breath, but sometimes I can't.

When you look at the air quality reports there are quite a few days in the summer when it's recommended to limit physical activity outdoors, and while this is occasionally due to forest fires, it's mostly from motor vehicles. Physical exertion while breathing fine particulates, oxides of nitrogen, unburned hydrocarbons, and ground level ozone seems like a pretty bad health choice, even if the drivers behaved perfectly.

Again, I'm not trying to minimize the hazard of oblivious or aggressive drivers, I'm just saying that right now in addition to coping with that risk you also have to breathe in some very toxic stuff, and people will ride more and drive less when the air is cleaner.

I wonder what New York City does that eliminates tail pipe emissions to the point that so many people walk?

Electric vehicles are great and we should go full speed ahead on EVs. That being said, because of (1) the emissions involved in their manufacture, and (2) the additional energy capacity needed to support full vehicle electrification, we cannot meet our climate goals by relying on EVs alone. Reducing VMT is simply essential, there is no path to the needed scale of carbon reduction otherwise.

Not biking because of tailpipe exhaust seems to be largely a boogeyman of folks who don't want to bike in the first place (either searching for an excuse not to do so or as part of an anti-bike argument). In most parts of the city, exhaust largely isn't a perceptible issue.

And for what it's worth, research shows the cardiovascular benefits outweigh the harms done by breathing the fumes. That's not going to convince anyone new to get on a bike, but it's still an important finding.

Xandrex, I generally agree about the benefits outweighing the harm, but there are times when it just doesn't seem worth it, like when you're on the downwind side of 6 lanes of idling cars by the Walker and getting all the fumes from the tunnel.

FWIW, the several people I've talked to who have mentioned the emissions have been women, all of whom ride enthusiastically around the lakes and on parkways.

Yeah, I don't disagree that some of those people exist - just that most people who I've seen make that excuse haven't always been genuine. Regardless, it's clearly a reality for some, and even if it isn't, we'd still want to reduce emissions.

That said, I'm surprised anyone would cite the Hennepin/Lyndale bottleneck specifically as a particularly problematic area. That's a pretty short stretch with curb-and-boulevard protected bike lanes. You'll never be sitting directly behind a car there. The real threats seem to be the Groveland and Oak Grove intersections. I'd say the worst spot for exhaust is Nicollet (both the Mall and Avenue), where there is a lot of bike traffic often stuck behind buses and cars at intersections.

Not totally on board with these posts being moved. I was hoping to bring this back around to Sam, where I started it, and discuss the assumptions that he and his colleagues on the planning commission are working from. It's uplifting to hear him say that we should be more like New York or Paris, but with our much colder winters and no subway system in the earliest planning phase, how much would driving (regardless of the energy source) have to be reduced to get in their league? Fifty percent?

Are you saying that moving to electric cars by itself will mean that people shouldn’t take fewer car trips?

It’s amazing how much private capital is being spent on self driving cars.

I got a letter today about a proposed A.V. Shuttle Pilot Project. The route is 1.5 miles along Linden Ave, Willow Ave and Orchard Ln in WBL just north of 694. The route runs between some senior housing and the ymca. The picture included looks like the A.V. from the super bowl. The route would run on weekdays 10am to 2pm for a 12 month period.

There are community meetings next week. I plan to go and will report back.

Meeting tonight.

I've been banging on this gong for a while, but using these AV's for collector shuttles that feed or distribute from our mainline transit service on short, predictable routes seems like a match made in heaven. Getting rid of the labor cost of the driver allows these vehicles to be smaller and still economical.

I wholeheartedly agree. I think it's the first big step towards AV. We will need a more robust transit system to make it work though. It will work well in Oslo right now.

Thank you!

I've been screaming about this also. The easiest tech to crack has to be a fixed predictable shuttle routes that fill in where buses, LRT doesn't, where you learn the local rules and traffic, can have a few local humans monitoring and helping shuttles and can even do things on the route infrastructure ( signs, light posts) to help AVs in bad weather etc.

How much easier it to figure that out than individual cars going anywhere and everywhere in the world?

And that's the use case that could take off because how super cheap would it be to have 20 mph EV driverless shuttles going back and forth, or in a loop, in fairly dense near train or bus stops.

Super cheap EV shuttles mean they could be super frequent, which is killer app for transit: frequency + proximity = ridership.

Such circulators set up to be great last mile complement to LRT and BRT stations we have at every 0.5 miles - maybe you live 1.5 miles from a LRT or BRT stop - and would take it but 20 minute walk and 0-10 minute at station wait in bad weather just enough to discourage - now a shuttle come to within a block of you every 0-5 minutes, and gets you to station in 5 minutes and is shelter from cold, heat, rain and snow.

The last mile was mentioned at the meeting as a future hope for this type of project.

Given the WBL pilot project is just that a “pilot” and serving elderly and disabled, there will always be a co-pilot with the vehicle. Also the Newtrax rep mentioned that they see these as easing the hiring in the future. No need to hire a driver, just an assistant for those that need help. Different skill sets.

Some were upset by the 20mph plan. It’s a 30 mph road. But of course people speed. ¯\_(ツ)_/¯
