Question on 'display_history' function

See original GitHub issue

Hi ! I met some problems when I wanted to use display_history function.

I used env.configure({"show_trajectories": True}) to implement it. I’m sure it can be use in current version of highway-env. But i dont know why the error happened on my version. I used the env since 3 months ago. I know there are some differents in the code between that time and now.

I want to know if the function cant be used in that old version (3 months ago) or I should use other environment configurations ?

I wonder what is going on, all Vehicle classes have required (at least) 4 arguments for very a long time… You can remove vehicle.velocity if it seems to be working fine, but it might have hidden unintended consequences. I would rather advise to uninstall highway-env and reinstall the latest version.
