SLEX radar vs speedometer reading

[cast_no_shadow]

Tried waze and speedometer comparo earlier. Looks like 2-3 kph slower yung speedometer * speeds over 80-90kph. May lag lang ng konti yung sa waze (split second) reading, btw steady rpm and speed ko yun ginawa. (Obviously not an accurate measurement but a good basis din naman pala yung speedometer).

OT

How do you check your speed using waze?
