I think its more a case of jumping off the bandwagon. Not believing everything people say, especially when they are making delicate announcements that they don't want to alienate customers. Then reach your own rational conclusions.
Pre-Brexit people warned of the potential damage to the car industry. Now it has happened, albeit exacerbated by global slow down in China, Brexiteers want to bury their head in the sand and say it was just a weird coincidence the Nissan and Honda job losses occurred now on the even of Brexit, after 35 successful years in the UK. Choo choo to you too.
