You can get used to it and adapt yourself to driving it smoothly. The first thing to remember is that an I-SHIFT is not a 'press and go' automatic. It is an automated manual in which electronics and machinery dip the clutch and change the gears of a manual transmission. The greatest torque reaction and greatest strain on any gearbox and clutch is in the change up from 1st to 2nd. So the electronics damp the acceleration between upward changes. This is the "lurch" you feel. But if you anticipate the changes and drive with a lighter throttle, they will be perfectly smooth. You can also take over by using the paddles. Automated manuals vary considerably from car to car. The best I have driven was the Dualogic in a FIAT QUBO, which even managed full throttle upchanges quite smoothly. But the Jazz I-SHIFT is one of the best of the rest. So if I was you I'd persevere, and if you do I think you'll get the hang of it. Honda needs to think about providing a 5-speed torque converter auto in the Jazz, as it does in other World markets and already does in the UK in the Civic as an alternative to its I-SHIFT.
