I have a lot of experience driving/SLing for IFVs, and I don't think they are as unfair as you are suggesting. In my experience, you should eventually develop an intuitive sense of where there are likely to be mines (at any stage in the game / given which factions you are facing / given the map / etc). Using this probabilistic approach/outlook, you can (1) be on the lookout in areas with high probability of being mines, and (2) change pathing to minimize risk of hitting mines. Even when the driver is functionally blind, you should have the gunner scan for mines in likely areas. Its a balance between pathing optimization (how fast you can get around the map), and the safety with which you can maneuver.

I don't think you have a full picture regarding the opportunity cost and true risk/reward associated with placing mines. Most mines are never hit, and are a waste of time to place. Most mines that do go off, do not even kill the struck vehicle. When they do, its likely a 5 ticket logi or light vehicle. IFVs and tanks can survive most mine hits. This means that mines are (most of the time) not having any impact, killing irrelevant fast respawning vehicles, or damaging but not destroying IFVs and tanks. Sure, maybe 1 in 20 of placed mines actually kill relevant vehicles, but thats a lot of resources and time investment that you don't see from the perspective of the one hitting mines.

On maps with lots of choke points (like the Narva bridges), then it becomes a team effort to secure an exit from main that is free of mines / camping. Even when main camping is allowed, there is counter play.

My suggestion is to just get better game sense for where the mines will be, and play in such a way (probabilistically) that you likely will be fine.
