Discussion Overview

The discussion centers on the effectiveness of speed limits and road design in relation to driver behavior and safety. Participants explore various aspects of road hazards, the impact of visual cues on driving speed, and the implications of road design choices on accident rates and driver interactions. The conversation includes theoretical considerations, practical observations, and personal experiences related to traffic management and urban planning.

Discussion Character

  • Debate/contested
  • Conceptual clarification
  • Technical explanation
  • Exploratory

Main Points Raised

  • Some participants argue that speed limits are ineffective as drivers tend to drive based on the perceived conditions of the road rather than posted limits.
  • One participant mentions that non-hazardous obstacles could be used to mark roadways, providing safer spaces for pedestrians and cyclists while holding careless drivers accountable for vehicle damage.
  • Another participant shares personal observations of changes in driver behavior following the installation of traffic calming measures, such as traffic circles and curb bumpouts.
  • Concerns are raised about the confusion and potential hazards created by new road designs, which may lead to mixed driving behaviors and road rage.
  • Some participants express frustration over the costs associated with road design changes that seem to complicate rather than simplify driving conditions.
  • One participant highlights the difference in road safety outcomes between the US and UK, suggesting that slower speeds correlate with fewer accidents, while questioning the relevance of the video’s conclusions.

Areas of Agreement / Disagreement

Participants express a range of views on the effectiveness of speed limits and road design, with no clear consensus reached. Some agree on the ineffectiveness of speed limits, while others highlight the importance of speed reduction for safety. The discussion remains unresolved regarding the best approaches to improve road safety and driver behavior.

Contextual Notes

Participants note limitations in the discussion, such as the lack of sidewalks in certain areas and the potential disconnect between highway and urban road safety measures. There are also unresolved questions about the impact of driver behavior on accident rates and the effectiveness of various traffic management strategies.

Driving is a legal liability. Why would anyone volunteer to drive?
You're right, it's a completely pointless risk if there's alternatives that make it optional. As is the skydiving I've done once, and my pilot's license. Why indeed.... 🤔
Is it risk-taking males, between the ages of 18 and 28, who use it as a substitute for tribal warfare, in the hope they will be seen as an alpha male by a trophy mate.
I think that's pushing it. For the record, I started flying lessons in earnest(minus two "discovery" flights) at age 44.

All the biggest mistakes we make in life, are made in the very short period between the first and second childhood.

But no, you can't guarantee that at all.
Yes, I can guarantee I'm 100% focused on the road. But no, I cannot guarantee I won't have an accident ... like it is the case for any other driver.

Why would you drive 50mph over the limit?
First, I said 50 km/h; Second, in any case, pleasure.

Also, as I said in a previous post, driving below a certain speed (different for each driver in different conditions) gives you a false sense of security, your mind starts wandering out of boredom, and you are thus less alert.

sophiecentaur said:
At best, it is anti-democratic.
Wouldn't that imply that a democratic choice has been made at some point about what the speed limit should be? I can't even imagine what the criteria are to set one. For example, what is an acceptable death rate before we say "this is fast enough"?

What do you think about autobahns in Germany, where vehicles restricted to speeds in the range 60-100 km/h (buses, trucks, cars & motorcycles pulling trailers) share the road with vehicles driving the suggested 130 km/h, and even a few going over 250 km/h?

There is no evidence that German highway safety is much worse than anywhere else, even if you can find better somewhere else. (Although worldwide comparison can be difficult as there are many differences between countries in their geography, economy, traffic growth, highway system size, degree of urbanization and motorization, and so on.)

German organizations calling for a speed limit on autobahns often have more arguments about reducing pollution and improving traffic flow rather than road safety.

When everyone follows speed limits, there is a predictability to traffic flow that reduces the chance of accidents. When some drivers break that compact, the chance of an accident increases.

In my opinion, arguing to the contrary is simply incorrect. We have many freedoms, but the freedom to speed faster than others on the road is not one of them.

One case I've observed in Houston is the desire to get on and off the freeways as quickly as possible. Some drivers will pass on the left, while others will do so on the right, or worse, hide in your blind spot. So, although you may know a car is there, it becomes very dangerous to switch to the right lane for slower traffic or to exit the freeway.

In another case, attempting to pull out onto a street with traffic moving at varying speeds is inherently dangerous without the predictability of speed limits; yet, some drivers fail to recognize the importance of these limits in regulating traffic flow. This is when traffic accidents are most likely to occur.

In any case, this is a good time to close this thread, as we have exhausted the topic to the point where our cars are worn out, and it's time to switch to walking and public transportation.

Thank you all for the stimulating conversation.
