Cloverleaf ramps to enter an expressway: an idea whose time has past?

Ever happen to you? You're on a frigging cloverleaf ramp exiting off some road on to an expressway and get behind a semi (who HAS to be cautious) or some overly cautious driver who drives a mere 20-25 mph on the loop when the acceleration lane to merge into the expressway is rather short and you MUST be up to 55 mph, MINIMUM, per state law before you merge (barring inclement weather, of course), what do you do? Blow up your engine trying to accelerate hopelessly fast or merge into traffic at 35 and pray you don't get killed? (You know, there IS a reason they set a minimum. It's not just there for the fucking hell of it.)

So what is y'all take on this? As I see the issue, there's only a few possible solutions:

1) Deem cloverleaf ramps to be unsafe and pass a law against them for new construction (since 'ex post facto' laws are forbidden by the Constitution) and then go back and retrofit all of the dangerous previously existing ones?

2) Lengthen the acceleration lanes coming into the expressway to allow for a more sensible rate of acceleration?

3) Widen the cloverleaf by having a turn then a reasonable straightaway to accelerate with a very gradual turn to the acceleration lane?

4) Declare that the cloverleaf is a better alternative than to turn left across a busy road (which can be mitigated with traffic signals, mind you) or to do what is often called a "Michigan left" whereas you either (depending on the situation), turn right or go straight to turn left via an approved U-turn lane?

Keep in mind that should you choose number 4, that you need to convince me that traffic signals and a "Michigan left" are MORE unsafe than a cloverleaf.

Good luck on that one!
