The Wotmobile is the term given to the privately owned vehicle of the J-idols fans especially the RW (rich wota) as a mean of transportation for attending Hello! Project concerts, handshake events or other fan club activities. The Wotmobiles are usually the typical boxxy-shaped,futuristic Japanese car although modified sportscar and BMWs can also be found depending on the ability of the fan to buy the car that they want.
The Wotmobiles usually have large storage to store the owner merchandises, to be sold or just making crop-circles like patterns from Morning Musume's fans. Micro-MPVs are the popular choice for The Wotmobiles as these MMPVS are cheap, consume less fuel, small and nasty. These vehicles are quick enough to get them to the destinations without a fuss.
Comparing with Batman's Batmobile(s), The Wotmobiles do not have the ability to change to Batpod/Batmissile, no stealth mode, no cauldron-size exhaust that shoots fire (although some have Nitrous Oxide installed), and no other Batman shits. The most important things for the owners are to have cup holders for holding up coffees or energy drinks and the GPS system for the RWs or the map from the convenient store for the lower castes to provide them with all of the available alternative routes for them to get to the concerts, for example if they want to avoid the traffic jams and whatnot.

There are rumors that the fans want to change the term to "ザ・チャンバラ" (The Tumbler).
