Not only vehicles, that is false. What you should say is any unit but infantry. infantry tend to claim cover with less restrictions, but alll other unit types (monsters, bikers, cavalry, vehicles etc) has harder requirements.
It all depends on if you are using advanced terrain rules or not. At the basic level all terrain does is that it gives cover to any units within them. In that case there are no rules for obscured targets.
When you add the advanced rules for terrain, different terrain types have rules. Ruins and woods can benefit units that are obscured and within that terrain piece. Craters and barricades however only benefit infantry. If you have the rules book. read the advanced rules section. Then decide with your opponent if you prefer simple or complicated terrain rules.
If you want to take the terrain rules even further you can add their suggested "cities of death" expansion where the relative height of ruin floors can deny cover to enemys on lower levels. And staying in the same ruin for more thatn one turn gives +2 cover saves....
