Probably not. It could be in the middle of nowhere or on a road where the speed limit hasn’t been evaluated and the state default is 50. There are tons of roads like that in California or even some where the limit is in the 30s but it really shouldn’t be and locals are in the 60s usually.
There’s no reason to follow unreasonable rules even when you’re driving a death machine. Especially when not following the rules has an essentially near 0 difference in hurting someone with your cage of death(not trying to be sarcastic with cage of death). Many of these roads are designed for much higher speed limits but just have not been evaluated by the government for their speed limit and possibly never will be or they will be evaluated at a much lower than reasonable speed. For example the speed limit of most California freeways is 65 traffic moves at 80 regularly and sometimes when people are feeling frisky up to 90. Neither of those speeds are unreasonable when everyone around you is also doing them and people are used to those situations or understand they will be in those situations. A great example is Germany where parts of their freeways have no speed limit where people are doing in excess of 120 mph and semis are also using it at under 60.
