I agree with Piske and qqqqqqqqqqqqqqqqqqqq - only official "kiirtee" as defined by liiklusseadus should be mapped as highway=motorway.

To revert all EE motorways back to trunk means reverting 14 changesets. These also include other changes as well. I assume it might be better to change 699 individual way elements back to highway=truck? If there are no objections I can do this myself quite easily.
