There is a bit of a difference you can cover a lot of ground in a car.(yes I know bikes can too, but a lot don't) Our government here in Australia doesn't have it's head up it's but and has introduced some sensible rules. You need exercise so you can ride your bike, or go for a jog, but not stupidly far from home. You must socially distance. Groups of unrelated or non households can't exceed 2 people. You can't just drive around randomly, you have to have a reasonable excuse. You can go to the beach, but if the beach gets crowded it gets closed immediately. Some states allow fishing, but again near home and with social distance. Basically if the mob stuff it up, it gets closed down and people get fined or locked up.
Since I need to drive for work sometimes I can definitely see way less traffic. The "great" thing for us here is that the USA is a perfect example of how not to deal with CV-19, the government goes "we don't want to end up like the USA" and the population on average goes "nope, that would be a bad idea" and toes the line.
