</div>I vaguely recall hearing a long time ago, that cars are not mekabel tumah, because they are not keilim, because they are too large. Despite being movable, it still counts as a binyan. I think the shiur was 40 seah. Or so my memory says.<br>
</blockquote></div><br>K'li ha-ba'ah b'midah (aka k'li he-asui l'nachas) is only a din by wood, hide, or cloth, as is learned out from a hekesh to a sack (which is intended to be movable even when full) in Vayikra 11:32 - see Chagiga 26b and Rambam Hil. Keilim 3:2 and 3:3. <br>
<br>RJDBleich in his article on airplanes that I previously mentioned (Tradition 36:4) mentions several other reasons why this heter would not apply to a vehicle, including that it has wheels (so is movable) and that it is used for seating (as excepted by Tos' Shabbos 44b DH Mucheni).<br>
