 Is one tenth of c close? At that speed time dilation is easy to observe.
 Time dilation is observed at the speed of an aeroplane.
 Oscillators currently studied in laboratories will in near future permit
the detection of time dilation at walking speed.
 

The problem with SRT:
if 'at rest' is indistinguishable from any other velocity:
how then could you assign any velocity to any object in the force free space of SRT?
In that space you always need to have some other object, in respect to which you measure velocity.
That reference object is usually regarded as being at rest.
E.g. we could regard our home upon planet Earth as being at rest.
So, we walk down the street at walking speed and regard ourselves as rather slow.
But that is, of course, wrong, because the Earth rotates once per day and circles in a huge ellipse around the Sun once per year (together with our home).
The entire solar system swirls around the galactic center and our home galaxy around the local cluster.
But which speed is actually ours while walking along our street???
