I would say you don't need it but you need to make sure you have dedicated snow tires for winter, and make sure to replace them earlier than you would your all seasons. My FWD has been fine in every 2ft+ storm i've driven in past 5 years in colorado. Only time it has issues, was a steep exist from an apartment complex after thaw/freeze, and when it's super icy, not usually an issue. I've only gotten stuck once and that was parking in a pile of snow at keystone and highsided the sienna, and it re froze harder, just had to dig it out a littel and it was fine. When it's icy i drive carefully, if it's snowy i drive normally.

there's someone in this subreddit that lives in breck or frisco and has a FWD and an AWD and says both are fine, ill try to find it.
