First off, game is fantastic and have very few qualms, however this one seems like a basic error that is easily fixable.
Settings on measurements suggest that Fahrenheit is an ‘English’ measurement, which is not true. If players wanted a true British driving experience the setting would read as below…
English - Celsius, Yards, Miles
Default should be - Fahrenheit, Yards, Miles
Metric remain as - Celsius, Metres, Kilometres
Currently (and rather annoyingly as a British player), there is no true ‘English/British’ setting that allows for Celsius, Yards and Miles. Would suggest amending the ‘Default’ and ‘English’ settings to more accurately reflect user preferences by region.
