Pregunta fallos en mi código

Errores:

proj.h:146: error: expected initializer before ‘&’ token
proj.cpp: In function ‘int main(int, char**)’:
proj.cpp:22: error: no match for ‘operator<<’ in ‘std::cout << p.std::_List_const_iterator<_Tp>::operator* [with _Tp = vehicle]()’

bueno por ahora este es mi codigo, espero que me podais ayudar, muchas gracias de antemano

salu2!!
