VD: public transportation is good in my city. we have an excellent bus system. The traffic moves quickly, except at rush hour, however, we need more public parking. there aren't enough parking spaces downtown, so it always takes too much time to find a space.

Tớ đoán chừng bên VN kêu radar speed gun là “Dụng cụ để bắn tốc độ”.



radar speed gun = speed gun = speed radar gun.

Loại radar thì dùng sóng vi ba còn không thì có thể dùng tia laser.

camtieu is correct. speedometer is the tool to measure the velocity of the vehicle itself.

camtieu is correct. speedometer is the tool to measure the velocity of the vehicle itself.

FYI
Speedometer [SPEED METER] is a device that measures how fast an object/vehicle is moving (speed), [NOT the velocity]. However, a GPS navigation system (GPS receiver) could be considered as a velocity read-out device.
The bottom line
Velocity = speed + direction.
Velocity ≠ speed.
