How much time do I save if I speed?
The average driver saves 26 seconds a day by speeding. People think it saves time. Maybe it does occasionally, if you run through a yellow light to avoid stopping for a minute. But, the time savings, on average, is about 2 minutes a week.
The 'rule' itself is quite straightforward: if the speed limit is (for example) 30mph, the rule states that you won't get a speeding ticket unless you are going 10% plus 2 mph faster than the limit.
The average fuel economy decrease from 50 to 60 mph was 12.4%; from 60 to 70 mph the average decrease was an additional 14%; and from 70 to 80 mph the average decrease was another 15.4%. The best fuel economy is typically obtained when the vehicle is traveling at the lowest speed in the vehicle's highest gear.
For every 2,458 hours saved by speeding on 100 km per hour (62 mph) roads, there's one injury and there's one fatality for every 24,450 hours saved. There are a few additional costs worth mentioning: increased stress, traffic tickets and increased fuel costs.
While 1x speed would play a video at normal speed, 2x speed would play a video twice as quickly and thus save you half the time.
While in many cases these accusations are true, new research suggests that the overwhelming majority of speeders on roads are actually driving safer than those who are sticking to a speed limit that is too low.
So is 10% + 2mph Real
The answer is yes and no. You can be prosecuted for going just 1mph over the limit but it's all about being proportionate but the police guidance hasn't changed.
In the eyes of the law, you're liable for a speeding fine as soon as you exceed the limit. So if you're doing 31mph in a 30 limit or 71mph on motorway, you're breaking the law.
Most police forces have a tolerance of 10% plus 2 mph above the limit before a speed camera 'flashes'. So on a 30 mph road, a camera wouldn't normally activate unless a car drove past at 35 mph or faster. So for example, On a 70 mph stretch of motorway, the threshold would go up to 79 mph.
Generally speaking, yes. Cruise control can help you become more fuel-efficient and can help you save an average of 7-14% on gas thanks to its ability to maintain a continuous speed. In comparison, the constant change in acceleration and deceleration of the driver placing their foot over the pedals can eat more gas.
At what speed is gas most efficient?
About 55 miles per hour is the optimum speed for most cars. Kick it up to 65 mph and you are 8 percent less efficient; at 80 mph you are 28 percent less efficient. Slowing down can also mean reducing your carbon footprint.
While vehicles reach optimal fuel economy at different speeds, gas mileage usually decreases rapidly at speeds above 50 miles per hour (mph).
When you drive your car too fast, you are putting a lot of stress on the engine. This can cause the engine to overheat and eventually fail, leading to expensive engine repairs or even replacing the engine entirely.
Driving slower than the surrounding traffic is more likely to cause an accident than speeding, according to research. Driving too slowly can make other drivers around you constantly brake and speed up. It can be frustrating for other drivers, cause confusion and could lead to an accident.
Biologically speaking, driving fast is accompanied by a surge of adrenaline which causes blood pressure and heart rate to jump. Some are more susceptible to this high than others, but the research has shown that in general it hits men harder than women.
100% faster means speed is increased by 100%, i.e., double speed. So, you don't reduce time by 100%, but by 50%. If it's 200% faster, you get 3x speed. In your example, you'd charge the battery in 2.5 and 1.6 minutes, respectively.
Saying something is 50% faster means the same as being 150% faster. Or 100% faster could also be 200%, depending on subtle language choices.
In the fall of 1973, in response to the OPEC oil embargo, President Nixon issued an executive order mandating a 55 mph national maximum speed limit. The following January, Congress made it official and passed a "temporary" one-year continuation of the limit.
Generally, the faster a driver is going, the higher the risk of collision and the odds that a crash will cause a fatality. Back in 1984, it was estimated that the 55 mph speed limit saved up to 4,000 lives per year.
Slowing down also puts less stress on the engine, transmission, and tires, enabling them to run cooler and last longer.
Can you get a speeding ticket for doing 34 in a 30?
Guidance from the National Police Chief's Council (which used to be ACPO) is that motorists should not be penalised unless they are over the speed limit by 10% plus 2mph. In a 30mph zone that is 35mph. However, it is only guidance and has no legal force.
It has been questioned whether this would count as one offence or two. The general rule is that where 2 speeding offences are deemed to have been committed 'over the course of the same journey, e.g. within a few minutes of each other, the Court can impose only one set of points for the two or more offences.
Don't believe the urban legend that most cameras are just empty boxes, but it is true that not all speed cameras flash. Ultimately, there's really only one way to tell whether you've been nabbed by a roadside speed camera, and that's the appearance of a fine notice in the post.
Speed awareness courses
For the speed awareness course, the speed of the offence must fall within the criteria stated below: 30 mph up to and including 42 mph. 40 mph up to and including 53 mph.
Band A offence example
If you were caught travelling at a recorded speed of 36mph in a 30mph zone you would be prosecuted under Band A rulings. Three points would go on your licence.
