Clearly, with a failed transaction, ~ $60 worth of ETH would just go waste🗑

Why should the transaction fail?
Even if you set the gas price to 1 Gwei, the transaction will never fail, unless you set the gas limit to lower than the required amount.
In the case the network is so busy and you use a low gas price, your transaction will take long time to be confirmed. It may take months, but it won't fail.

You can’t proceed the transactions with a lower fees, error will appear.
Seriously failed transactions for unknown reasons are possible because i experience the same thing. Though in my experience, I’ve learn not to change the default fees so it will push through because every time I choose the lower option, it fails.
