Without wheel speed sensors, distance and speed errors quickly accumulate.

With a particle filter and enough computation, that error can be eliminated after the fact. Ie. At the time you won't know where you are, but after you get out of the metro and the particle filter reconverged you'll know where you were with more accuracy at some point in the past.

Ah. I see. Thanks very much for that insight - so that's why it's possible, but not generally interesting and/or widely pursued.
