When did Boston reduce the speed limit to 25 mph?

The recent study focused on Boston, which lowered the default speed limit on city streets from 30 mph to 25 mph beginning January 9, 2017. Researchers looked at speeds before and after the lower limit took effect and compared them to similar streets in Providence, Rhode Island, where the speed limit remained the same.

What’s the average speed of a Mini Moke?

These mostly top out at 75kmh and are capped for local low energy vehicle laws. For instance, in France they are only 45kmh, but that’s actually cool because 14-year-olds and people busted for drunk driving can drive them.

What’s the risk of being hit by a car at 25 mph?

A pedestrian struck by a vehicle at 25 mph has a 25 % risk of sustaining a serious or fatal injury, and the risk jumps to 50 % at 33 mph and 75 % at 41 mph, according to the AAA Foundation for Traffic Safety. Those statistics are troublesome, as outside of urban areas, speed limits are on the rise.

A dealer has AT LEAST a tech2 scanner which has graphing capabilities. Its easy, you graph the data of all 4 wheels (3 with a solid axle), stop the car and the wheel the loses signal is the culprit. Usually under 5 mph the bad will read 0 mph indicating a lock wheel to activate abs.

Can a bad check engine light be a bad TPS?

The check engine light will randomly turn on and off even if the car is running smoothly without any jerks and stalling. This is often the first ever symptom of a bad TPS. Using a code reader, you should be able to confirm whether a faulty TPS is the culprit or a different component.

Why does my car make noise when I go over 20 mph?

If you hear the noise above 20 mph it’s most likely a wheel bearing noise but it’s not a bad idea to check the tire tread to be sure the tires are not chopped or worn uneven. If you what to leave me more details about the noise I may have a more definitive answer to what may be the problem.

Why does my steering wheel vibrate when I go over 50 mph?

Be sure to have the rotor checked and skimmed or replaced completely if needed. A worn out or rusted brake caliper pin may be another culprit for vibrations. You will probably feel your steering wheel start to vibrate around 50 miles per hour, which will intensify as you increase your speed, and you’ll sense a burning smell when you stop.

Why is harmonic mean used for speeds, not arithmetic mean?

In summary, when you are calculating the average of ratios of two quantities, (such as speed being the ratio of distance to time), if the values of the denominators are equal (equal time for each segment), then the average over all segments is the arithmetic mean of the ratios for for all of the segments.

When is harmonic mean used for all segments?

If the values of the numerators are equal (equal distance for each segment), then the average over all segments is the harmonic mean of the ratios for all of the segments.

Why does my car hesitate when I step on the accelerator?

Instead of going faster by stepping on the accelerator pedal, the speed will be reduced. The vehicle may even stumble entirely during these seconds. This is what it means when the car engine hesitates. It is usually the result of a problem with the air and fuel mixture within the combustion chamber.

How can you accelerate a car up a hill?

You can accelerate it up the hill by applying a positive acceleration. Until you slow it down entirely and it stops and turns around, you’re applying a positive acceleration to it, and it’s slowing down. Positive and negative are both relative terms: they depend on direction.

Why does my car lose power going uphill?

Reasons Your Car Loses Power Going Uphill 1) Bad Fuel Filter. You can’t have a good working engine without fresh pure gasoline flowing into it at all times. If you don’t have a good fuel filter to prevent the impurities of the fuel from flowing into the engine, then it could ultimately jeopardize the performance of your engine.

What causes a car to run lean on a hill?

If the fuel filter is not changed for a long time, eventually the particles and sediment from the gas tank will build up and clog the filter, restricting fuel flow. If the flow of fuel is restricted too much, not enough will be able to reach the fuel injectors and the car is likely to run lean.

Why does my Dodge Ram have vibration at 60 mph?

Last fall I purchased a used 2016 Ram 1500 with 72K miles. The dealer had just replaced the tires. I noticed I had a slight vibration around 60 mph but thought the tires and new and had just been balanced when they were replaced. Anyway, I took it to a tire shop.
