Where have I suggested that?

You suggested they may apply "sanctions" against us. Remember?

we will have to stick to the rules about level playing fields for tariffs.

So will EU.
We will not want to impose tariffs on food so non EU food will be cheaper for us.
EU farmers will take a hit. Poor them.

You mentioned cars. Unless we get free trade with EU we may want to apply a tariff which will make EU cars much less competitive here. Poor them. Non EU cars are already charged so will not be effected.
