Relativistic effects occur at all speeds.
The magnitude of the effect at speed v is given by the ration
r(v) = √(1 - v²/c²)
where c = 30000 km/s
Consider v = 100 mph, which is approximately 160/3600 km/s.
If you calculate r(v) you get around 0.9999999999999.
That is too close to 1 to measure the difference.
