The entire point of the thread is that Ostheer T3 comes much later than Soviet T3 making "rushing" a PIV to counter the enemy's light vehicles hard because by the time the PIV hit's the field the enemy will already have extremely plentiful counters.
Soviet player is spending fuel for tech + 70 fuel for T-70. When that P4 comes out, Soviet player is SOL cause he will only have an AT gun as hard counter. Whermacht player can hold off with Pak, PGs and Grens and not to mention teller mines until T3. But yes I concede, the scout car could use a bit of a punch against light vehicles.
