True, but:

1. You didn't have to count 151 million votes in the UK election

2. You didn't have to wait a few days for mail-in ballots that were delayed in transit to arrive

3. You didn't have to do this in the middle of a global pandemic that required poll workers to stay 6 feet apart

Generally the US election results can be predicted the same day, this year had additional challenges due to extremely high turn-out, high use of mail-in ballots, and limited number of pool workers due to pandemic.

In my opinion, elections should be done using paper ballots, and those ballots are counted using electronic tabulation machines. After a batch of ballots are counted, a random sample of them are selected and manually counted. Should the results match, then you can have a high certainty of the accuracy of the count. Electronic tabulation machines are actually more accurate than hand-counting, and by hand counting again, you reduce the risk of the machines making "mistakes" due to technical glitches or malicious backdoors etc.

There were 32,014,110 in the last UK general election, which is one fifth of the US total, but then the population is also (roughly) one fifth of the US’.
