But it's unlikely for EU nations to significantly damage trading relationships with the UK. Germany, for example, exports a huge volume of cars to the UK and it comprises a significant portion of German GDP. Yes, there's volatility around exactly how such a trade deal will get worked out, but it's unrealistic to lump "access to European markets" into one big ball and assume that Brexit means that whole topic will be impacted negatively.
In reality, most significant European trading partners with UK just want to keep on trading with them mostly as they have been, and will work out deals that allow such trading to mostly continue. There doesn't seem to be much reason to think such trade deals will be radically changed in a way that damages anyone for the long term.
