Send function with hash

I know my x.to_s is not working and I need to use .send(something) but I cannot get the syntax right. If you can show me the correct send syntax I'd appreciate it.

h = 
@cars.each do|x| 
  h["x.to_s"] = 0 


If you mean to use the string representation of x as a hash key, remove the quotation marks:

h[x.to_s] = 0
