Why VFR weather minimums increase above 10000 MSL?

Accordingly, you'll need more visibility and distance from the clouds to see and avoid other aircraft. High speeds increase closure rates, so you'll have less time to react to oncoming traffic. If you're flying in Class E or G airspace, your visibility requirement above 10,000' MSL is 5SM, day or night.

VFR aircraft also must maintain a horizontal distance of 1sm from clouds while operating in Class E at and above 10,000ft. Below 10,000ft, the increase in TAS is reduced due to the lower altitudes. Therefore, the minimum forward flight visibility can be reduced from 5sm to 3sm.

The VFR Cruising Altitude rule does not apply below 3,000 feet AGL. There are some altitudes, however, that pilots seem to choose for level flight. Close to sea level they are 1000, 1500, 2000 and 2500. They are easy to read and remember on an altimeter.
