Speed sensor needs to be replaced in the engine, look speed sensor up for your vehicle
Velocity tells you the speed and the direction it's going. Speed only tells you the speed, with no direction.
only if they are the same size
The speed dialing option is not only good for its convenience on dialing numbers fast but if used the right way while driving; while at a light or a pause in traffic flow speed dialing can be utilized very effectively while driving.
It is not, but the engine works harder. You generally want to keep the RPM's as low as possible while driving. If you are going to be driving for a long time at the same speed, then it's better to enable overdrive no matter how fast you are going. Not only will your engine last longer, but you get better fuel mileage!
The distance is the same no matter what driving speed is used, only the driving time is altered.
Your only recourse may be to attend Traffic School in California. Doubt seriously that California will let you do that school in Arizona.
first question is : does this only happen after going over bumps in road ? if so look for loose connection , like ground to dash connection. Has any work been done on instrument cluster recently or radio replaced recently ? No, It happened when I was going down a hill, I realised when getting petrol that my passanger door had locked itself, then when I went home earlier I realised that my door had locked itself aswell, why is that?
Velocity as opposed to speed is a vector and is therefore much more useful. For example when driving in a car your speedometer tells you your speed in Mph or KMph. This however does not give you information on where you are going, it only tells you how fast. You could be going north, south, east or west. Velocity on the other hand is a vector, which means it gives you direction and magnitude. So you know the car's speed and direction. Therefore velocity is more important in describing how a storm is moving because it tells you where the storm is going and how fast it is going.
Your question doesn't give much detail but the car may not go into gear while you're driving (manual only) because the car's speed and engine speed are not suitable for the gear. E.g. If you're driving at 100km/h (60mph) it could become very difficult to change down to first gear.
You can automatically be at fault in an auto accident if you are the only driver involved; you were the driver who was not obeying the speed limit; if you were the driver who was not using safe driving rules; if you were breaking a law; if you were impaired. The most common cause for automatically being at fault is driving too close to the car ahead of you for the speed you are going and driving over the speed limit. None of these conditions are 100% automatically your fault but very close to that, especially if others involved in the accident were not doing any of the above.

Speed only tells how fast something is going, while velocity tells speed and direction.
