Roundabouts are obstructions to emergency vehicles & should be removed.

They work in the developed world, why not in racing towards second world America? Most fire trucks or ambulances aren't tractor trailer rigs - and if those can make it, so can emergency vehicles. I don't buy it. Time to evolve.

Too many cars/too little road is every day here roughly between 7am-7pm. You probably don't have the Puget Sound passive aggressive stumble either, probably created by too much coffee and too little sunshine.
Growing up over there, I remember my mother would run chains on her car constantly, my dad never bothered.

What is it with the truck and SUV vehicle classes that bring out the roid rage?
5 am this morning in Chicago, a Mercedes suv with 3 guys and a woman in it pulls up to a parked Escalade, and someone in Mercedes fires through windows of Escalade hitting and severely injuring a passenger. Escalade driver starts a 3 mile chase of the Mercedes, crashes into it, and it then Mercedes hits a minivan in an intersection. The 3 guys and a woman in the Mercedes get out of it and run away.

Yeah, I'm not seeing the strength of the argument against them on account of emergency vehicles. Those should be slowing down and using caution when passing through intersections anyway, so traffic circles aren't going to be a significant issue. If the responders crash in an intersection, they can't very well respond now can they?

Life in the big city! No, to be serious, stuff like that is just sad.
Are you feeling okay today xrunner? That post was not well-written (in contrast to your other posts). Hoping all's well....

And it's not like they usually fly down the road at triple digit speeds either, so I don't see the harm. Roundabouts are common in many countries, all of whom have emergency vehicles.

What a mess. Sounds like a criminal justice system failure.

Since traffic is continually flowing in and out of the roundabout and is not controlled by a signal, there is no time when a pedestrian can be reasonably certain that a vehicle will not pass over the crosswalk. Roundabouts can also be difficult for visually impaired pedestrians to determine the moment when it is safe to cross as many utilize traffic sounds to determine when a roadway is clear. Additionally, the route pedestrians must take around a roundabout is longer than the route they would take to walk through many signalized intersections.
Bicyclists can travel through a roundabout either as a vehicle (within the roundabout) or as a pedestrian (walking their bicycle). Some multi-lane roundabouts utilize an adjacent one-way trail where bicyclists approach the roundabout on-street, merge with the side trail via a ramp, travel around the roundabout on the trail, and then re-merge with the street via another ramp. This option presents some challenges with motor vehicles yielding at crossing points (similar to pedestrian issues described above). Notably, the reduced speeds of motor vehicles within the roundabout more closely match a bicyclist’s typical speed range (approximately 10 - 20 mph).
Emergency vehicles cannot speed through a roundabout like they can a signal light; they need to slow down and pass through the circle like regular traffic. Additionally, traffic signals offer the option for signal preemption to provide the green light to emergency vehicles; roundabouts require travelers to yield to emergency vehicles.
Illumination costs may be greater for a roundabout than a standard intersection as more lighting is typically required. More lighting may also be a concern of adjacent property owners, especially near residential areas
As with any new roadway configuration, highway maintenance staff will need to learn new snowplowing techniques
The construction of a roundabout to replace an existing traditional signalized intersection may result in the loss of some on-street parking if allowed near the former intersection.
The construction of a roundabout typically requires more right-of-way than a traditional intersection controlled by traffic signals or stops signs, which may increase the cost of a roundabout installation if right-of-way must be purchased.
Roundabouts may work in Europe where the cars and streets are much smaller, but over here it is not uncommon to see a 45’ motor coach pulling a toad, or a ¾ Ton pickup hauling a 5th wheel, or a tandem axle trailer with boat.
Roundabouts are not recommended, but wider intersections are because they are safer and handle the traffic with more efficiency.

Pedestrians = crosswalks. Enforce the laws, no problem. Same for cyclists.
Tractor trailers can handle them - visit Whatcom County, with several roundabouts on a main shipping route headed in and out of Canada.
Snow plowing is a pretty weak argument against, you have to admit. Does Clark County even own a snowplow?
Anything to get away from 4-way stops or negligently maintained fuel wasting traffic signals is needed, and now.
