Another solution, even if not the best, is to change the stearing wheal with a larger one (driver has to do longer turns of the wheal, but the human power needed decreases), but on a Ka this would make it to get in/out the driver's seat. i would also suggest changing the stearing ratio, but this only in a garrage since it's tricky and hard to do by yourself (any GOOD combinations of these 2+ the tyre pressure should ease up a bit the stearing, but don't expect miracles)
