Tacoma and Tundra have the capability to switch between English and Metric
units.

testing, and constantly monitoring performance. Consumer opinion and

I'm looking for a new car but all your cars have displays that give
Fahrenheit only, why does Toyota assume everyone wants Fahrenheit? This is
a free country, Federal Law states that the metric system is the preferred
system for the US, why can't Toyota make a vehicle where I can get metric
units at the flip of a switch as is done in GM vehicles?
